Abstract
Immunoassays are efficient for the phytochemical analysis of various matrices. However, producing an appropriate recombinant antibody for small molecules is challenging, resulting in costly analyses. In this study, we aimed to develop recombinant fragment antigen-binding (Fab) antibodies against miroestrol, a potent phytoestrogen marker of Pueraria candollei. Two expression cassettes of Fab were established for the production of active Fab antibodies using SHuffle® T7 Escherichia coli cells. The orientation of variable fragment heavy chain (VH) and variable fragment light chain (VL) in the expression vector constructs influences the reactivity, stability, and binding specificity of the resultant Fab. Stability testing of antibodies demonstrated that Fab is a more stable form of recombinant antibody than a single-chain variable fragment (ScFv) antibody in all conditions. Based on the obtained Fab, the ELISA specifically detected miroestrol in the range of 39.06-625.00 ng/mL. The intra- and inter-assay precisions were 0.74-2.98% and 6.57-9.76%, respectively. The recovery of authentic miroestrol spiked into samples was 106.70-110.14%, and the limit of detection was 11.07 ng/mL. The results for P. candollei roots and products determined using our developed ELISA with Fab antibody and an ELISA with anti-miroestrol monoclonal antibody (mAb) were consistent (R2 = 0.9758). The developed ELISA can be applied for the quality control of miroestrol derived from P. candollei. Therefore, the appropriate expression platform of Fab resulted in the stable binding specificity of the recombinant antibody and was applicable for immunoassays.Key points• ELISAs with Fab has higher sensitivity than that with ScFv.• Fab is more stable than ScFv.• Fab-based ELISA can be used for miroestrol determination of Pueraria candollei.

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
Pueraria candollei is an ingredient of Thai herbal medicine, dietary supplements, and cosmetics. The in vitro and in vivo studies of this plant supported anti-osteoporotic activity and used for hormone replacement therapy. Deoxymiroestrol shows the most potent phytoconstituent in tuberous root of P. candollei with estrogenic activity. The quality controls are important for good agricultural practice (GAP) and good manufacturing practice (GMP) of plant-derived raw materials. The rapid detection of lateral flow immunoassay (LFIA) using colloidal gold is simply method, easy visualize detection and produce less waste than conventional chromatographic detection. In this study, LFIA for qualitative detection of deoxymiroestrol using antigen-binding fragment antibody (Fab) was developed. The result showed that the developed LFIA displays specific detection of deoxymiroestrol. Cross reactivity of this method was analyzed with miroestrol, isomiroestrol and methylisomiroestrol which showed 39.97%, 7.71% and 5.72%, respectively. After optimal condition, limit of detection (LOD) for deoxymiroestrol is 250 ng/ml. Plant samples were applied to strip test compare with indirect competitive ELISA using polyclonal antibody to confirm the application of LFIA. The results of LFIA method were comparable with those from ELISA. This developed lateral flow immunoassay can apply to detect deoxymiroestrol for the rapid testing. The developed method can use for quality control in plant samples as deoxymiroestrol is biomarker compound in P. candollei.

Abstract
KEY MESSAGE Plant expression platform is the new source of immunoglobulin G (IgG) toward small low-molecular-weight targets. The plant-made monoclonal antibody-based immunoassay exhibits comparable analytical performance with hybridoma antibody. Immunoassays for small molecules are efficiently applied for monitoring of serum therapeutic drug concentration, food toxins, environmental contamination, etc. Immunoglobulin G (IgG) is usually produced using hybridoma cells, which requires complicated procedures and expensive equipment. Plants can act as alternative and economic hosts for IgG production. However, the production of free hapten (low-molecular-weight target)-recognizing IgG from plants has not been successfully developed yet. The current study aimed at creating a plant platform as an affordable source of IgG for use in immunoassays and diagnostic tools. The functional IgG was expressed in Nicotiana benthamiana leaves infiltrated with Agrobacterium tumefaciens strain GV3101 with recombinant geminiviral vectors (pBY3R) occupying chimeric anti-miroestrol IgG genes. The appropriate assembly between heavy and light chains was achieved, and the yield of expression was 0.57 µg/g fresh N. benthamiana leaves. The binding characteristics of the IgG to miroestrol and binding specificity to related compounds, such as isomiroestrol and deoxymiroestrol, were similar to those of hybridoma-produced IgG (monoclonal antibody, mAb). The plant-based mAbs exhibited high sensitivity for miroestrol (IC50, 23.2 ± 2.1 ng/mL), precision (relative standard deviation ≤ 5.01%), and accuracy (97.8-103% recovery), as determined using quantitative enzyme-linked immunosorbent assay. The validated enzyme-linked immunosorbent assay was applicable to determine miroestrol in plant samples. Overall, the plant-produced functional IgG conserved the binding activity and specificity of the parent IgG derived from mammalian cells. Therefore, the plant expression system may be an efficient and affordable platform for the production of antibodies against low-molecular-weight targets in immunoassays.

Quantification of methylisomiroestrol, a phytoestrogen of Pueraria candollei, by enzyme-linked immunosorbent assay in comparison with high-performance liquid chromatography. J Pharm Biomed Anal 2020; 192:113674.

Abstract
Pueraria candollei is a phytoestrogen-rich herb used to treat estrogen deficiency disorders; however, quality control of P. candollei-related health products is required for consistency of clinical outcomes. Estrogenically active (+)-7-O-methylisomiroestrol could be a potential chemical marker that facilitates the prediction of the overall estrogenic activity of P. candollei. The analytical performance of ELISA using newly produced monoclonal antibodies against methylisomiroestrol was compared with HPLC analysis. The developed indirect competitive ELISA (icELISA) was highly sensitive to methylisomiroestrol for detection, with an LOQ of 2.9 ng/mL, whereas the LOQ was 1.15 μg/mL by HPLC. The results from method validation indicated acceptable precision (1.71-6.37 % and 0.13-2.40 %) and accuracy (99.23-102.54 % and 96.84-101.88 %) of the methylisomiroestrol analysis using icELISA and HPLC. These methods were effectively applied for the determination of the methylisomiroestrol content in P. candollei samples. Apart from the plant tubers, the stem was observed as a source of methylisomiroestrol. The developed ELISA was more effective than HPLC in detecting a small quantity of methylisomiroestrol in the plant samples [0.23 × 10-3% (w/w) to 0.628 × 10-3% (w/w) dry weight]. Therefore, the ELISA could be a useful tool for the standardization of P. candollei, which is the crucial step to improve the quality of plant-derived products.

Abstract
INTRODUCTION Miroestrol is the potent phytoestrogen isolated from White Kwao Krua (Pueraria candollei var. mirifica (Airy Shaw & Suvat.) Niyomdham, a Thai traditional medicinal plant. Nowadays, various health supplementary products featuring White Kwao Krua are available worldwide. A sensitive and rapid analytical method for quantification of miroestrol is necessary for quality control of these products. OBJECTIVES To prepare a single-chain variable fragment (scFv) antibody specific to miroestrol and develop a scFv-based enzyme-linked immunosorbent assay (ELISA) for quantitative analysis of miroestrol in plant materials and health supplementary products. METHODS A gene encoding anti-miroestrol scFv antibody was constructed and expressed in Escherichia coli SHuffle T7 strain. Anti-miroestrol scFv antibody was characterised and applied to ELISA. The developed scFv-based ELISA method was validated for its sensitivity, specificity, accuracy and precision. RESULTS Anti-miroestrol scFv antibody was highly specific to miroestrol. The scFv-based ELISA was applied to determine miroestrol in the range 0.06-7.81 μg/mL, with the limit of quantification of 0.06 μg/mL miroestrol. The accuracy of the assay was validated by its 95.08-103.99% recovery from the spiked miroestrol recovery experiment and in good correlation with the results from the monoclonal antibody-based ELISA. The relative standard deviation of the intra- and inter-assay were less than 6.0%. CONCLUSION The developed scFv-based ELISA was sensitive, specific, accurate, and precise for determination of miroestrol and useful for quality control of P. candollei plant raw materials and supplementary products.

Development of a simple and rapid method for the detection of isomiroestrol in Pueraria candollei by an immunochromatographic strip test. J Nat Med 2019; 73:577-583.

Abstract
Pueraria candollei (P. candollei) is a traditional Thai herb widely used for estrogen replacement therapy because it contains many unique chromenes that possess potent estrogenic activity, one of which is known as isomiroestrol. Since isomiroestrol is a promising compound that is solely present in P. candollei, it can be used as an identifying marker for standardization of P. candollei. Here, we developed a lateral-flow immunochromatographic strip (ICS) test using a colloidal gold nanoparticle-conjugated anti-isomiroestrol monoclonal antibody (12C1-mAb) for the detection of isomiroestrol in plant samples and products of P. candollei. The advantages of the developed ICS over an enzyme-linked immunosorbent assay are its simplicity and rapidity, as the ICS test can be completed 15 min after dipping the strip into the analyte solution. The detectable concentration of isomiroestrol was 7.0 µg/mL. Considering the demand for the standardization of P. candollei due to concerns regarding its quality, our ICS test using isomiroestrol as an identifying marker would be effective and useful to assess the presence of isomiroestrol.
