Abstract
INTRODUCTION The stem of the plant species Derris scandens (Roxb.) Benth. (DS) contains genistein-7-O-[α-rhamnopyranosyl-(1→6)]-β-glucopyranoside (GTG), which is a unique marker. Previous analyses of GTG using antibody-based immunoassays were compromised because of their high cross-reactivity with structurally related compounds of DS, thereby limiting their applicability in DS quality control. OBJECTIVE Conjugation of GTG with carrier proteins was achieved using the Mannich reaction to produce a highly specific monoclonal antibody (mAb) targeting GTG (anti-GTG mAb). METHODS The anti-GTG mAb was generated using hybridoma technology and characterised using an indirect competitive enzyme-linked immunosorbent assay (icELISA). Both lateral-flow immunoassay (LFIA) and icELISA were developed to detect and quantify GTG in DS raw materials and associated products. RESULTS icELISA using the anti-GTG mAb showed 100% specificity for GTG, with only 1.77% cross-reactivity with genistin and less than 0.01% cross-reactivity with other compounds. icELISA demonstrated a linear range for GTG determination between 62.5 and 2000 ng/mL. The limits of detection (LOD) and quantification were 49.68 and 62.50 ng/mL for GTG, respectively. The precision of the analysis ranged from 1.28% to 4.20% for repeatability and from 1.03% to 7.05% for reproducibility. The accuracy of the analysis ranged from 101.97% to 104.01% for GTG recovery. GTG levels determined via icELISA were consistent with those confirmed via high-performance liquid chromatography (HPLC) (R2 = 0.9903). Moreover, the LOD of LFIA for GTG was 500 ng/mL. CONCLUSION Immunoassays utilising specific anti-GTG mAbs were successfully developed, including LFIA for rapid GTG detection and icELISA for GTG quantification.

Abstract
In China, harmful algal blooms (HABs) are one of the most prominent ecological disasters in the coastal areas. Among the harmful algae species that cause HABs, Karen mikimotoi is a kind of algae that appear frequently. It can secrete hemolytic toxins and fish toxins such as glycolipids and unsaturated fatty, posing a significant threat to marine life. In order to establish a fast and effective detection technology for Karen mikimotoi that can be promoted and applied on site, we have developed a test strip which is based on monoclonal antibody technology and the colloidal gold immune-chromatography assay (GICA). The experimental results show that this test strip can detect different growth stages including growth, and stable and recession period of Karen mikimotoi. The detection results can be displayed within 3-15 min. It had high sensitivity and specificity, with a detection limit of 754 cells/mL. A colorimetric card was made to further determine the concentration of algae detected. What is more, we had developed a method that can be used for on-site enrichment of algae cells using a syringe to detect lower concentrations of Karen mikimotoi, with a minimum detection concentration of 100 cells/mL. Also the test strip was used for on-site testing along the coast of China. This test strip not only serves as a warning for the outbreak of red tide, but also provides a new approach for the development of rapid detection technology for red tide algae.

Abstract
The common carbamate insecticide aldicarb is considered one of the most acutely toxic pesticides. Herein, rational design was used to synthesize two haptens with spacers of different carbon chain lengths. The haptens were then used to immunize mice. The antibodies obtained were evaluated systematically, and a colloidal gold immunochromatographic strip was developed based on an anti-aldicarb monoclonal antibody. The 50% inhibition concentration and linear range of anti-aldicarb monoclonal antibody immunized with Hapten 1 were 0.432 ng/mL and 0.106–1.757 ng/mL, respectively. The cross-reactivities for analogs of aldicarb were all <1%. The limit of detection of the colloidal gold immunochromatographic strip was 30 μg/kg, and the average recoveries of aldicarb ranged from 80.4 to 110.5% in spiked samples. In the analysis of spiked samples, the test strip could accurately identify positive samples detected by the instrumental method in the GB 23200.112-2018 standard but produced some false positives for negative samples. This assay provides a rapid and accurate preliminary screening method for the determination of aldicarb in agricultural products and environments.

Abstract
Phytoproducts are involved in various fields of industry. Small-molecule (Mw < 900 Da) organic compounds can be used to indicate the quality of plant samples in the perspective of efficacy by measuring the necessary secondary metabolites and in the perspective of safety by measuring the adulterant level of toxic compounds. The development of reliable detection methods for these compounds in such a complicated matrix is challenging. The lateral flow immunoassay (LFA) is one of the immunoassays well-known for its simplicity, portability, and rapidity. In this review, the general principle, components, format, and application of the LFA for phytoproducts are discussed.

Abstract
A quantitative lateral-flow immunoassay using gold nanoparticles (AuNPs) conjugated with a monoclonal antibody (MAb) against saikosaponin d (SSd) was developed for the analysis of SSd. The AuNPs were prepared in our laboratory. The AuNPs were polyhedral, with an average diameter of approximately 18 nm. We used the conjugation between AuNPs and MAbs against SSd to prepare immunochromatographic strips (ICSs). For the quantitative experiment, the strips with the test results were scanned using a membrane strip reader, and a detection curve (regression equation, y = -0.113ln(x) + 1.5451, R² = 0.983), representing the averages of the scanned data, was obtained. This curve was linear from 96 ng/mL to 150 μg/mL, and the IC50 value was 10.39 μg/mL. In this study, we bring the concept ofPOCT (point-of-care testing) to the measurement of TCM compounds, and this is the first report of quantitative detection of SSd by an ICS.

Abstract
A lateral flow-based immunochromatographic strip was developed for the rapid detection of mitragynine (MG), a dominant alkaloid found in the leaves of kratom. Monoclonal antibody (mAb) against MG (anti-MG mAb) was conjugated to colloidal gold and used as a recognition probe. MG-ovalbumin conjugate (MG-OVA) and goat anti-mouse IgG were immobilized on the strip to produce a test zone and control zone, respectively. Based on the principle of a competitive assay, MG in a test sample competed with MG-OVA resident in the test zone to bind with colloidal gold-anti-MG mAb, resulting in an inverse relation of color intensity at the test zone and MG amount. The limit of detection (LOD) of the immunochromatographic strip is determined at 1 mg/mL of MG by visual assessment and 0.60 mg/mL by Image J analysis. The developed immunochromatographic strip can determine MG in kratom cocktails and kratom leaf samples. It could serve as a rapid and simple diagnostic kit for the detection of MG in kratom samples.

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
In this study, a rapid (within 10min) quantitative lateral-flow immunoassay using a quantum dots (QDs)-antibody probe was developed for the analysis of puerarin (PUE) in water and biological samples. The competitive immunoassay was based on anti-PUE monoclonal antibody conjugated with QDs (detection reagent). Secondary antibody was immobilized on one end of a nitrocellulose membrane (control line) and PUE-bovine serum albumin conjugate was immobilized on the other end (test line). In the quantitative experiment, the detection results were scanned using a membrane strip reader and a detection curve (regression equation: y=-0.11ln(x)+0.979, R(2)=0.9816) representing the averages of the scanned data was obtained. This curve was linear from 1 to 10μg/mL. The IC50 value was 75.58ng/mL and the qualitative detection limit of PUE was 5.8ng/mL. The recovery of PUE added to phosphate-buffered saline and biological samples was in the range of 97.38-116.56%. To our knowledge, this is the first report of the quantitative detection of a natural product by QDs-based immunochromatography, which represents a powerful tool for rapidly screening PUE in plant materials and other biological samples.

Abstract
INTRODUCTION Mulberroside A (MuA) is the major active anti-tyrosinase compound in the root bark extract of Morus alba L. (Moraceae). Typically, MuA is widely employed as an active ingredient in whitening cosmetics. A rapid and simple assay system utilizing a small quantity of test sample is essential for the detection of MuA in large number of samples. An immunoassay using highly specific MuA polyclonal antibodies may be useful for the determination of small quantities of MuA in test samples. OBJECTIVE To establish a rapid qualitative MuA test, an immunochromatographic strip test was developed using anti-MuA polyclonal antibodies (anti-MuA PAb). METHODOLOGY The qualitative assay was based on a competitive immunoassay where the detection reagent consisted of anti-MuA PAb colored with colloidal gold particles. The capture reagent was a MuA-ovalbumin (MuA-OVA) conjugate immobilized on the test strip membrane. RESULTS A sample containing MuA and the detection reagent were incubated together with immobilized capture reagent on a nitrocellulose membrane. When MuA was present, it competed with the immobilized conjugates on the strip membrane to bind a limited amount of colored antibodies; thus, a positive sample showed no color on the capture spot zone. The detection limit for the strip test was 2 µg/mL. The developed immunochromatographic strip test was utilized to determine MuA in plants, medical preparations and cosmetic samples. CONCLUSION This immunochromatographic strip test is advantageous as a rapid, simple and sensitive screening method for the detection of MuA in plant extracts, cosmetic samples and pharmaceutical products.

Abstract
INTRODUCTION Rhubarb, senna and sennoside-containing preparations are currently widely employed as purgatives. The major active components of these medications are sennoside A (SA) and sennoside B (SB). OBJECTIVE To develop an eastern blotting technique for the specific visualisation and easy determination of SA and SB in plant extracts for application in the standardisation and authentication of rhubarb and senna. METHODOLOGY SA and SB were separated by TLC, transferred to a PVDF membrane, treated with 1-ethyl-3-(3'-dimethylaminopropyl)-carbodiimide hydrochloride solution and finally treated with bovine serum albumin (BSA). The resulting membrane-bound SA-BSA and SB-BSA conjugates were linked to anti-SA and anti-SB monoclonal antibodies (MAbs) and then to secondary antibodies labelled with peroxidase. SA and SB were detected by visualisation of the peroxidase reaction products. RESULTS The limit of detection of the eastern blotting was 62.5 ng for both sennosides. The method was applied to the immunohistochemical localisation of SA in fresh rhubarb root. Phloem and radiate wood were found to contain higher concentrations of SA compared with other tissues (pith and bud) in agreement with results obtained by ELISA. The concentrations of SA in the phloem, radiate wood, pith and bud were 64.4, 48.1, 15.0 and 1.8 ng/mg fresh weight, respectively. CONCLUSION The technique described permitted the visualisation of small molecular weight compounds that had been bound to a membrane, using immunostaining. Owing to the specificity of the MAbs, the eastern blotting may prove to be a useful method for the identification of SA and SB in a background containing large amount of impurities.

Abstract
Monoclonal antibody against kanamycin was prepared, and competitive direct ELISA and immunochromatographic assay were developed using the antibody to detect kanamycin in animal plasma and milk. The monoclonal antibody produced was identified to be IgG1, which has a kappa light chain. No cross-reactivity of the antibody was detected with other aminoglycosides, indicating that the monoclonal antibody was highly specific for kanamycin. Based on competitive direct ELISA, the detection limits of kanamycin were determined to be 1.1 ng/ml in PBS, 1.4 ng/ml in plasma, and 1.0 ng/ml in milk. The concentration of intramuscularly injected kanamycin was successfully monitored in rabbit plasma with competitive direct ELISA. Based on the colloidal gold-based immunochromatographic assay, the detection limits of kanamycin were estimated to be about 6-8 ng/ml in PBS, plasma, and milk. The immunochromatographic assay would be suitable for rapid and simple screening of kanamycin residues in veterinary medicine. Screened positives can be confirmed using a more sensitive laboratory method such as competitive direct ELISA. Therefore, the assays developed in this study could be used to complement each other as well as other laboratory findings. Moreover, instead of slaughtering the animals to obtain test samples, these methods could be applied to determine kanamycin concentration in the plasma of live animals.

Abstract
BACKGROUND Reliable analytical methods are required to monitor neomycin residue levels in the livestock products. In particular, a more simple and rapid detection method is required in the veterinary fields. METHODS Competitive direct ELISA and immunochromatographic assay were developed using monoclonal antibody to detect neomycin in the animal plasma and milk. RESULTS No cross-reactivity of the antibody was observed with other aminoglycosides based on competitive direct ELISA methods, indicating that the antibody is highly specific for neomycin. Based on the standard curves, the detection limits were determined to be 6.85 ng/ml in PBS, 3.61 ng/ml in plasma, and 2.73 ng/ml in milk, respectively. Recoveries of neomycin from spiked plasma and milk at levels of 50-200 ng/ml ranged from 87% to 108%. Concentration of intramuscularly injected neomycin was successfully monitored in the rabbit plasma through competitive direct ELISA. Immunochromatographic method was also developed using colloidal gold-conjugated monoclonal antibody. Through this method, the detection limits were estimated to be about 10 ng/ml of neomycin in PBS, plasma, and milk. CONCLUSIONS Immunochromatographic assay developed in this study is suitable for the simple screening of neomycin residues in the veterinary field. Observed positives can be confirmed using a more sensitive laboratory method such as competitive direct ELISA.

Abstract
Competitive direct enzyme-linked immunosorbent assay (ELISA) and the immunochromatographic assay were developed using a monoclonal antibody to detect gentamicin in the animal plasma and milk. No cross-reactivity of the antibody was observed with other aminoglycosides based on competitive direct ELISA, indicating that the antibody is highly specific for gentamicin. On the basis of the standard curves, the detection limits were determined to be 0.9 ng/mL in phosphate-buffered saline (PBS), 1.0 ng/mL in plasma, and 0.5 ng/mL in milk, respectively. Recoveries of gentamicin from spiked plasma and milk at levels of 25-100 ng/mL ranged from 85 to 112%. The concentration of intramuscularly injected gentamicin was successfully monitored in the rabbit plasma through competitive direct ELISA. The detection limits were estimated to be about 6 ng/mL of gentamicin in PBS, plasma, and milk using the colloidal gold-based immunochromatographic assay, which is suitable for the simple screening of gentamicin residues in the veterinary field. Observed positives can be confirmed using a more sensitive laboratory method such as competitive direct ELISA. Therefore, the assays developed in this study could complement each other as well as veterinary field and laboratory findings.
