Immunological Separation of Bioactive Natural Compounds from Crude Drug Extract and Its Application for Cell-Based Studies. Antibodies (Basel) 2021; 10:antib10040048. [PMID: 34940000 PMCID: PMC8698370 DOI: 10.3390/antib10040048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2021] [Revised: 11/09/2021] [Accepted: 11/30/2021] [Indexed: 01/31/2023] Open
Abstract
In this study, we present a review on a useful approach, namely, immunoaffinity column coupled with monoclonal antibodies (MAbs), to separate natural compounds and its application for cell-based studies. The immunoaffinity column aids in separating the specific target compound from the crude extract. The column capacity was stable even after more than 10 purification cycles of use under the same conditions. After applying the crude extract to the column, the column was washed with washing buffer and eluted with elution buffer. The elution fraction contained the target compound bound to MAb, whereas the washing fraction was the crude extract, which contained all compounds except a group of target compounds; therefore, the washing fraction was referred to as a knockout (KO) crude extract. Cell-based studies using the KO extract revealed the actual effects of the natural compounds in the crude extract. One-step separation of natural compounds using the immunoaffinity column coupled with MAbs may help in determining the potential functions of natural compounds in crude extracts.

Abstract
An immunoblotting system ("eastern blotting") was developed for small-molecule herbal medicines like glycosides, with no conjugation function to the membrane. Briefly, the crude extracts of herb medicines were developed by thin-layer chromatography (TLC). The small-molecule herbal medicines on TLC plates were transferred to polyvinylidene fluoride (PVDF) or polyethersulfone (PES) membranes by heating. Antigen components were divided into two categories based on their function, i.e., their membrane recognizing (aglycone part) and fixing (sugar moiety) abilities. This procedure allows for the staining of only target glycosides. Double eastern blotting was developed as a further staining system for two herb medicines using a set of MAbs and substrates.

Abstract
Two cDNAs encoding type Ш polyketide synthase (PKS1) and chalcone synthase (CHS, PKS2), were cloned from fresh leaves of Plumbago zeylanica L. (P. zeylanica). Their heterologous expression revealed that PKS1 catalyzed the formation of five α-pyrones from three to six acetate units by accepting acetyl-CoA and malonyl-CoA. In contrast, PKS2 catalyzed the formation of naringenin and bisnoryangonin by accepting p-coumaroyl-CoA and malonyl-CoA. Naringenin is thought to be involved in the biosynthesis of various bioactive flavonoids. PKS2 can be used to molecular breeding to enhance the production of these useful secondary metabolites via its overexpression.[Formula: see text].

Artificial color light sources and precursor feeding enhance plumbagin production of the carnivorous plants Drosera burmannii and Drosera indica.

Abstract
Plumbagin is the main pharmacologically active compound of carnivorous plants in the genera Drosera. It possesses various pharmacological activities, including anticancer and antimalarial activities, and is used in traditional medicine. In this study, we reported a sustainable production system of plumbagin by adding sodium acetate and L-alanine as precursors to in vitro cultures of Drosera burmannii Vahl and Drosera indica L. In addition, plumbagin production was reported in the cultures subjected to different color LED lights. The highest plumbagin level (aerial part 14.625 ± 1.007 mg·g-1 DW and root part 1.806 ± 0.258 mg·g-1 DW) was observed in D. indica cultured under blue LED light for 14 days, and further culturing did not increase plumbagin production. In addition, plumbagin enhancement by precursor feeding (9.850 ± 0.250 mg·g-1 DW, 1.2-fold) was observed in the aerial part of D. indica treated with 50 mg·L-1 sodium acetate for 3 days. Comparing both plants, up to 700-fold higher plumbagin was observed in D. indica than in D. burmannii. Moreover, in both plants, the aerial part accumulated higher plumbagin (up to 10-fold) than the roots. This is the first report on the effect of artificial LED lights on the plumbagin level of Dorsera plants. The culturing of D. indica under blue LED light showed enhanced plumbagin levels and suggests a fast and simple system for the in vitro production of plumbagin.

Abstract
Lithospermic acid B (LSB), the major water-soluble ingredient of Salvia miltiorrhiza (Danshen), has been shown to be an active ingredient responsible for the therapeutic effects of this traditional Chinese herb used to treat cardiac disorders. This study aimed to develop an indirect competitive enzyme linked immunosorbent assay (ELISA) for the detection of LSB. Firstly, LSB was chemically conjugated to a modified oil-body protein, lysine-enriched caleosin, recombinantly expressed in Escherichia coli. Antibodies against LSB (Ab-LSB) were successfully generated by immunizing hens with artificial oil bodies constituted with the LSB-conjugated caleosin. Western blotting showed that Ab-LSB specifically recognized LSB, but not the carrier protein, lysine-enriched caleosin. To detect LSB via indirect competitive ELISA, LSB was conjugated with bovine serum albumin (LSB-BSA) and coated on a microplate. The binding between Ab-LSB and LSB-BSA on the microplate was competed dose-dependently in the presence of free LSB with a concentration ranging from 5 to 5 × 104 ng/mL. The IC50 value was approximately determined to be 120 ng/mL for LSB regardless of its complex with a metal ion of Na+, K+ or Mg2+.

Abstract
Harringtonine (HT) is a promising natural product that is mainly isolated from plants of the genus Cephalotaxus. Due to its remarkable antileukemic activities, HT has been utilized clinically in China for the treatment of acute promyelocytic leukemia (APL). No antibody that recognizes free HT has been reported to date due to the difficulty of preparing antigen conjugates in which haptens bind to a carrier protein. To overcome this difficulty, we focused on sodium periodate (NaIO4), which catalyzes unique oxidative reactions; the resulting conjugates enabled the production of a highly specific monoclonal antibody (MAb) against HT (MAb 1D2) and the establishment of an indirect competitive enzyme-linked immunosorbent assay (icELISA) for the determination of HT. Further analysis revealed that MAb 1D2 was produced by the HT3 (8-carbonyl HT)-based conjugate antigen; HT3 was synthesized by a NaIO4-mediated oxidative reaction. The minimum detectable concentration for HT in the icELISA system was found to be 0.76 ng mL-1, which is approximately 13 to 160 times more sensitive than a conventional HPLC system. Several validation analyses revealed that the icELISA using MAb 1D2 is sufficiently accurate, reliable, and sensitive to assess small amounts of HT in plant samples.

Abstract
We developed an immunochromatographic assay (ICA) that enables rapid analysis of salvinorin A (Sal A) in Salvia divinorum within 10 min. The result shows that no Sal A in other samples of Lamiaceae plants was detected, but it could recognize Sal A among other substances in complex samples. The main advantage of the ICA is its high performance in combination with low cost, simplicity, and speed. Our newly developed combined ICA/indirect competitive ELISA(icELISA) system enables analysis of large numbers of samples over short periods of time without cumbersome pretreatments in complex mixtures. This method can complement other instrumental analyses for salvinorins, and could be used to deter S. divinorum abuse.

Abstract
Owing to the widespread application value, monoclonal antibodies (MAbs) have become a tool of increasing importance in modern bioscience research since their emergence. Recently, some researchers have focused on the production of MAbs against medical plant-derived natural products (MPNP), the secondary metabolites of medical plants. At the same time, various immunoassay methods were established on the basis of these MPNP MAbs, and then rapidly developed into a novel technique for medical plant and phytomedicine research in the area of quality control, pharmacological analysis, drug discovery, and so on. Dependent on the research works carried out in recent years, this paper aims to provide a comprehensive review of MAbs against MPNP and the application of various immunoassay methods established on the basis of these MAbs, and conclude with a short section on future prospects and research trends in this area.

Abstract
Wogonin 7-O-β-D-glucuronide (Wgn) is a bioactive flavone present in the dried root of Scutellaria baicalensis Georgi. To generate a monoclonal antibody (MAb) against Wgn, BALB/c mice injected with Wgn-bovine serum albumin yielded splenocytes that we fused with SP2/0 myeloma cells using the polyethylene glycol method. We obtained a hybridoma designated 315A that produced a MAb reactive to Wgn. The anti-Wgn MAb 315A was applied to an indirect competitive enzyme-linked immunosorbent assay (icELISA) to quantify Wgn. Subsequent validation revealed that icELISA using the 315A anti-Wgn MAb is an accurate and reliable method for the quantification of Wgn in S. baicalensis.

Abstract
Electrochemical detection strategies employing semiconductor quantum dots (QDs) open up new opportunities for highly sensitive detection of biological targets. We designed a new assay based on microbead linked enzymatic generation of CdS QDs (Microbead QD-ELISA) and employed it in optical and electrochemical affinity assays for the cancer biomarker superoxide dismutase 2 (SOD2). Biotinylated antibodies against SOD2 were immobilized on the surface of polyvinyl chloride microbeads bearing streptavidin. In order to prevent any non-specific adsorption the microbeads were further blocked with bovine serum albumin. The analyte, SOD2 was captured on microbeads and labeled with alkaline phosphatase-conjugated antibody linked with mouse antibody against SOD2. Hydrolysis of para-nitrophenylphosphate by immobilized alkaline phosphatase triggered the rapid formation of phosphate-stabilized CdS QDs on the surface of microbeads. The resulting semiconductor nanoparticles were detected by fluorescence spectroscopy, microscopy, and square-wave voltammetry (SWV). The electrochemical assay based on the detection with square-wave voltammograms of Cd2+ ions originating from immobilized CdS QDs showed linearity up to 45 ng mL-1, and the limit of SOD2 detection equal to 0.44 ng mL-1 (1.96 × 10-11 M). This detection limit is lower by 2 orders of magnitude in comparison with that of other previously published assays for superoxide dismutase. The electrochemical assay was validated with HepG2 (Human hepatocellular carcinoma) cell lysate containing SOD2.

Abstract
INTRODUCTION Genistein 7-O-[α-rhamnopyranosyl-(1→6)]-β-glucopyranoside (GTG) is a major bioactive compound in Derris scandens. It is responsible for anti-inflammatory activity by inhibition of cyclooxygenase and lipoxygenase. There are many commercial products of D. scandens available in Thailand. OBJECTIVE To develop an enzyme-linked immunosorbent assay (ELISA) for the quantitative analysis of GTG in plant material and derived products using a polyclonal antibody. METHODS An immunogen was synthesised by conjugating GTG with a carrier protein. The polyclonal antibody against GTG (GTG-PAb) was produced in New Zealand white rabbits. The ELISA method was validated for specificity, sensitivity, accuracy, precision and correlation with HPLC. RESULTS The polyclonal antibody was specific to GTG and genistin within the range of compounds tested. The GTG ELISA was applied in the range 0.04-10.00 μg/mL with a limit of detection of 0.03 μg/mL. The recovery of GTG in spiked Derris scandens extracts ranged from 100.7 to 107.0%, with a coefficient of variation less than 7.0%. The intra- and inter-assay variations were less than 5.0%. The ELISA showed a good correlation with HPLC-UV analysis for GTG determination in samples, with a coefficient of determination (r2 ) of 0.9880. CONCLUSION An ELISA was established for GTG determination in Derris scandens. The GTG-PAb can react with GTG and genistin, but genistin has not been found in the plant. Therefore, the ELISA can be used for high throughput quality control of GTG content in D. scandens and its products. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
We propose a new approach of an indirect enzyme-linked immunosorbent assay (ELISA) for determination of D-glutamic acid (D-Glu) using a monoclonal antibody against D-glutamic acid (D-Glu-MAb), which recognizes D-Glu-glutaraldehyde (GA) molecule but not D-Glu molecule. Human serum albumin (HSA) was coated on an immunoplate and reacted with D-Glu via GA to produce D-Glu-GA-HSA conjugates in situ in the well to be recognized by D-Glu-MAb, which enabled the development of an indirect ELISA for the determination of free D-Glu. In this indirect ELISA, D-Glu can be specifically detected with limit of detection of 7.81 μ g/mL. Since anti-conjugate antibodies are often produced, even though anti-hapten antibodies are desired, this new approach could be very useful as an application of anti-conjugate antibodies to the development of quantitative analysis for detecting hapten.

Abstract
Soy isoflavones are known as major bioactive compounds in soybean (Glycine max), which is an indispensable food. Despite their utility, the consumption of isoflavones has recently been limited because they exhibit oestrogenic and topoisomerase II inhibitory effects. To assess their intake limitation, accurate, sensitive, and effective quantitative analyses are necessary. In this study, we produced the monoclonal antibody (MAb) against daidzin (DZ) and applied it to an indirect competitive enzyme-linked immunosorbent assay (icELISA) for the simultaneous determination of DZ and genistin (GEN), which are known as two major soy isoflavone glycosides in soy products. Using the DZ-MAb, we developed a sensitive icELISA method, where the limit of detection for DZ and GEN was 1.95ng/ml. Several validation analyses revealed that the icELISA is sufficiently accurate and sensitive to be used to assess the overconsumption of soy isoflavones, which would lead to the safe dietary intake of soy products.

Abstract
Most of the functions of D-amino acids (D-AA) remain unclear because of little analytic methods for specific detection/determination. In this study, a highly specific monoclonal antibody to D-glutamic acid (D-Glu-MAb) was produced using a hybridoma method. Characterization of D-Glu-MAb by indirect enzyme-linked immunosorbent assay (ELISA) revealed that it has high selectivity against D-Glu-glutaraldehyde (GA) conjugates, while no cross-reaction was observed when 38 other kinds of AA-GA conjugates were used. Moreover, subsequent indirect competitive ELISA disclosed that an epitope of D-Glu-MAb is a D-Glu-GA molecule in the conjugates, suggesting that D-Glu-MAb could be a useful tool to investigate the functional analysis of D-Glu in immunostaining.

Abstract
BACKGROUND Clopidol is mainly used for the prevention and treatment of coccidiosis, which poses a serious potential hazard to public health, in veterinary medicine. The aim of this study was to prepare monoclonal antibodies (mAbs) against clopidol (CLOP) and develop an immunoassay for detecting CLOP residues in chicken tissues. After derivation, CLOP hapten was conjugated to carrier proteins to synthesize the artificial antigen, and immunized Balb/C mice were employed to screen mAbs. RESULTS A sensitive hybridoma named C1G3 was screened out and two indirect competitive enzyme-linked immunosorbent assay (icELISA) standard curves were established. For the traditional two-step assay the linear range was from 0.06 to 98 ng mL(-1) , with half-maximal inhibitory concentration (IC50 ) and limit of detection (LOD) values of 2.76 ng mL(-1) and 0.03 ng mL(-1) respectively, while the rapid one-step icELISA had a working range from 0.08 to 102 ng mL(-1) , with IC50 and LOD values of 3.52 ng mL(-1) and 0.03 ng mL(-1) respectively. It was also indicated that a 10-fold dilution in chicken muscles gave an inhibition curve almost the same as that obtained in phosphate-buffered saline. When applied to spiking tests in chicken samples, the correlation coefficient (R(2) ) between concentrations added and measured was 0.9534. CONCLUSION The results of this study suggest that the immunoassay described is a promising alternative for screening CLOP residues in biological matrices and is suitable for routine diagnostics.

Abstract
Salvinorin A (1), the main active constituent in Salvia divinorum, is a highly selective kappa-opioid receptor agonist with hallucinogenic effects, which is regulated in several countries. In the present study, a monoclonal antibody (mAb) against 1 was prepared, and an indirect competitive enzyme-linked immunosorbent assay (icELISA) system was developed for the detection of salvinorins. To raise mAbs against 1, salvinorin B (2) hemisuccinate was synthesized and used to prepare the immunogen 2-bovine serum albumin conjugate. This technique was used to prepare a hybridoma cell line, 3D5, which secreted a mAb that recognized 1. The mAb was shown to have specificity for 1 and other salvinorins in cross-reactivity tests. The intra-assay calibration range by icELISA using the mAb against 1 was 0.0195-0.625 μg/mL. After validating the icELISA using intra- and interassays, a recovery experiment and analysis of several plants in the family Lamiaceae, including S. divinorum, confirmed that the analytical method based on ELISA is not only simple but also precise, accurate, sensitive, and sufficiently reliable. The results indicate that icELISA is a useful tool in the identification of S. divinorum.

Abstract
Two different recombinant antibodies, a single-chain variable fragment (scFv) and an antigen-binding fragment (Fab), were prepared against artemisinin (AM) and artesunate (AS) and were developed for use in an enzyme-linked immunosorbent assay (ELISA). The recombinant antibodies, which were derived from a single monoclonal antibody against AM and AS (mAb 1C1) prepared by us, were expressed by Escherichia coli cells and their reactivity and specificity were characterized. As a result, to obtain sufficient signal in indirect ELISA, a much greater amount of a first antibody was needed in the use of scFv due to the differences of the secondary antibody and conformational stability. Therefore, we focused on the development of the recombinant Fab antibodies and applied it to indirect competitive ELISA. The specificity of the Fab was similar to that of mAb 1C1 in that it showed specific reactivity toward AM and AS only. The sensitivity of the icELISA (0.16 μg/mL to 40 μg/mL for AM and 8.0 ng/mL to 60 ng/mL for AS) was sufficient for analysis of antimalarial drugs, and its utility for quality control of analysis of Artemisia spp. was validated. The Fab expression and refolding systems provided a good yield of high-quality antibodies. The recombinant antibody against AM and AS provides an essential component of an economically attractive immunoassay and will be useful in other immunochemical applications for the analysis and purification of antimalarial drugs.

Abstract
A chemiluminescence enzyme immunoassay based on magnetic microparticles (MmPs-CLEIA) was developed to evaluate serum α-fetoprotein (AFP) in parallel with traditional colorimetric enzyme-linked immunosorbent assay (ELISA). A systematic comparison between the MmPs-CLEIA and colorimetric ELISA concluded that the MPs-CLEIA exhibited fewer dosages of immunoreagents, less total assay time, and better linearity, recovery, precision, sensitivity and validity. AFP was detected in forty human serum samples by the proposed MPs-CLEIA and ELISA, and the results were compared with commercial electrochemiluminescence immunoassay (ECLIA) kit. The correlation coefficient between MPs-CLEIA and ELISA was obtained with R2=0.6703; however, the correlation between MPs-CLEIA and ECLIA (R2=0.9582) was obviously better than that between colorimetric ELISA and ECLIA (R2=0.6866).

Abstract
A single-chain variable fragment antibody (scFv) against plumbagin (PL) accumulated the PL production in the hairy roots of Plumbago zeylanica. Recombinant Agrobacterium rhizogenes (ATCC 15834) containing an scFv gene against PL (PL-scFv) were obtained through triparental mating and transformed into P. zeylanica to induce PL-scFv protein in the hairy roots. Up to 40 μg recombinant PL-scFv were expressed per milligram of soluble protein in transgenic P. zeylanica hairy root cultures. The mean PL content obtained from transgenic hairy roots (12.24 μg/100 mg dry weight) exhibited 2.2 times higher than those obtained from wild-type (5.48 μg/100 mg dry weight). The high correlation between the PL-scFv expression level and PL content of the recombinant plants suggested that the PL biosynthesis pathway had been modulated by the expression of PL-scFv protein in the hairy roots of P. zeylanica.

Abstract
Plumbagin (PL; 5-hydroxy-2-methyl-1, 4-naphthoquinone) is an important secondary metabolite, mainly produced in the Plumbago zeylanica L. (Plumbaginaceae). A single-chain variable fragment (scFv) antibody, fusion of the variable regions of the heavy chain and light chain of immunoglobulin against PL (PL-scFv) was expressed by Bac-to-Bac Baculovirus Expression System using Spodoptera frugiperda (Sf9) insect cells and characterized to investigate potential use of PL-scFv as a tool for plant immunomodulation. Functional PL-scFv expressed in the Sf9 insect cells were purified using cation exchange chromatography followed by immobilized metal ion affinity chromatography (IMAC). The yields of the purified PL-scFv in the culture supernatant and Sf9 insect cells were 2.0 mg and 5.2 mg per 1 liter of Sf9 culture medium, respectively. Recombinant purified PL-scFv was then characterized by the indirect competitive enzyme-linked immunosorbent assay (ELISA). The cross-reactivity and sensitivity of PL-scFv expressed in Sf9 insect cells were compared with PL-scFv expressed in Escherichia coli and its parental anti-plumbagin monoclonal antibody (MAb 3A3) secreted from hybridoma cells. Intriguingly, the specificity of the PL-scFv expressed in Sf9 insect cells was found to be different from that expressed in E. coli and parental MAb 3A3, although the detectable level (0.2-25 μg/mL) was the same in ELISA using each antibody. Even more interestingly, the characteristics of PL-scFv, which have wide cross-reactivity against 1,4-napththoquinone, suggest its potential use as a tool for plant immunomodulation not only for breeding Plumbaginacea family containing PL but also for breeding other medicinal plants containing bioactive naphthoquinones.

Abstract
AIM To generate a polyclonal antibody against sarsasapogenin and to develop an indirect competitive enzyme-linked immunosorbent assay (IC-ELISA) method for the pharmacokinetic study of Sarsasapogenin in rats. METHODS The antigen of sarsasapogenin was produced using an active ester method and subsequently used for raising polyclonal antibodies in rabbits. The specificity and sensitivity of the antibody were measured by IC-ELISA. Using the ELISA method, sarsasapogenin levels were measured in the serum of rats after an oral dose of 100 mg/kg. RESULTS Polyclonal antibodies raised against sarsasapogenin-bovine serum albumin were generated and showed a high reactivity to sarsasapogenin. The antibodies exhibited minor cross-reactivity to ruscogenin (23%), diosgenin (22%), 25 (R, S) ruscogenin l-O-[beta-D-glucopyranosyl (1-->2)][beta-D-xylopyranosyl (1-->3)]-beta-D-fucopyranoside (26%) and no cross-reactivity to diammonium glycyrrhizinate and notoginseng R1. The detection range of sarsasapogenin by this ELISA method was approximately 2.4-760 ng/mL. The recovery rates of 10 ng/mL, 100 ng/mL, and 500 ng/mL were in the range of 91.0%-96.2% for intra-assay and 89.0%-92.0% for inter-assay. The coefficients of variation (CV%) for intra- and inter-assays at the three different sarsasapogenin levels were 3.1%-8.3% (n=6) and 6.0%-14.1% (n=6), respectively. CONCLUSION The IC-ELISA method is a sensitive test for the determination of sarsasapogenin concentration in rat plasma and for pharmacokinetic (PK) studies.

Abstract
Methyl jasmonate, 50 microM, 0.5 mg yeast extract/l and 100 mg chitosan/l stimulated plumbagin production in Drosera burmanii whole plant cultures after 6 days of elicitation. Yeast extract (0.5 mg/l) was the most efficient enhancing plumbagin production in roots of D. burmanii to 8.8 +/- 0.5 mg/g dry wt that was 3.5-fold higher than control plants.
