Abstract
Plants are the cradle of the traditional medicine system, assuaging human or animal diseases, and promoting health for thousands of years. However, many plant-derived medicines contain toxic alkaloids of varying degrees of toxicity that pose a direct or indirect threat to human and animal health through accidental ingestion, misuse of plant materials, or through the food chain. Thus, rapid, easy, and sensitive methods are needed to effectively screen these toxic alkaloids to guarantee the safety of plant-derived medicines. Antibodies, due to their inherent specificity and high affinity, have been used as a variety of analytical tools and techniques. This review describes the antigen synthesis and antibody preparation of the common toxic alkaloids in plant-derived medicines and discusses the advances of antibody-based immunoassays in the screening and detection of toxic alkaloids in plants or other related matrices. Finally, the limitations and prospects of immunoassays for toxic alkaloids are discussed.

[PMID: 35540925 PMCID: PMC9077121 DOI: 10.1039/c7ra12810j] [Citation(s) in RCA: 32] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2017] [Accepted: 12/15/2017] [Indexed: 11/21/2022] Open
Abstract
Gold nanoparticle (AuNP)-based optical assays are of significant interest since the molecular phenomenon can be examined easily with change in the color of AuNPs. Herein, we report the development of a dipstick using a AuNP-labeled single-chain fragment variable (scFv) antibody for the detection of morphine. The scFv antibodies for morphine were developed using phage display-based antibody library. Immunoglobulin variable regions of heavy (V H)- and light (V L)-chain genes were connected via a glycine-serine linker isolated from murine immune repertoire and cloned into the expression vector pIT2. The scFv was produced in Escherichia coli HB2151, yielding a functional protein with a molecular weight of approximately 32 kDa. The morphine scFv was labeled with gold nanoparticles and used as an optical immunoprobe in a dipstick. The competitive dipstick assay characterized the ability of the scFv antibody to recognize free morphine. The detection range was 1-1000 ng mL-1 with a limit of detection (LOD) of 5 ng mL-1 under optimal conditions, and the IC50 value was 14 ng mL-1 for morphine. The developed optical dipstick kit of scFv antibody was capable of specifically binding to free morphine and its analogs in a solution in less than 5 min and could be useful for on-site screening of a real sample in blood, urine, and saliva.

Abstract
The use of optical biosensors for studying macromolecular interactions is gaining increasing popularity. In one study, 1514 papers that involved the application of biosensor data were identified for the year 2009 alone (Rich and Myszka, J Mol Recognit 24:892-914, 2011), the sheer volume and variety of which present a daunting task for the burgeoning biosensor user to accumulate and decipher. This chapter is designed to provide the reader with the tools necessary to prepare, design, and efficiently execute a kinetic experiment on Biacore. It is written to guide the Biacore user through basic theory, system maintenance, and assay setup while also offering some practical tips that we find useful for Biacore-based studies. Many kinetic-based screening assays require rigorous sample preparation and purification prior to analysis. To highlight these procedures, this protocol describes the kinetic characterization of single chain Fv (scFv) antibody fragments from crude bacterial lysates using an antibody affinity capture approach. Even though we specifically describe the capture of HA-tagged scFv antibody fragments to an anti-HA tag monoclonal antibody-immobilized surface prior to kinetic analysis, the same methodologies are universally applicable and can be used for practically any affinity pair and most Biacore systems.

Abstract
INTRODUCTION Immunosensor for illicit drugs have gained immense interest and have found several applications for drug abuse monitoring. This technology has offered a low cost detection of narcotics; thereby, providing a confirmatory platform to compliment the existing analytical methods. METHODS In this minireview, we define the basic concept of transducer for immunosensor development that utilizes antibodies and low molecular mass hapten (opiate) molecules. RESULTS This article emphasizes on recent advances in immunoanalytical techniques for monitoring of opiate drugs. Our results demonstrate that high quality antibodies can be used for immunosensor development against target analyte with greater sensitivity, specificity and precision than other available analytical methods. CONCLUSION In this review we highlight the fundamentals of different transducer technologies and its applications for immunosensor development currently being developed in our laboratory using rapid screening via immunochromatographic kit, label free optical detection via enzyme, fluorescence, gold nanoparticles and carbon nanotubes based immunosensing for sensitive and specific monitoring of opiates.

Abstract
Listeria monocytogenes is an important food-borne pathogen with an extremely high mortality rate (approximately 30%). Therefore, a highly sensitive, reproducible and rapid assay for its detection is vital. L. monocytogenes cells employ two surface bound proteins, Internalin A (InlA) and Internalin B (InlB) to promote invasion into host cells. Recombinant forms of both proteins were previously cloned and expressed in Escherichia coli. In this paper we describe how the InlB protein was sub-divided into three shorter overlapping peptide fragments yielding truncated functional protein of M(R) 23, 35 and 45 kDa, respectively. Purification of the InlB fragments by immobilised metal affinity chromatography (IMAC) was optimised and confirmed by electrophoresis and Western blotting. Identification of the antibody binding regions was achieved by probing the expressed polypeptide domains with a panel of antibodies and antibody fragments. The cloned peptide fragments were also used to develop novel fluorescence-based immunoassays incorporating quantum dots. The application of quantum dot-labelled anti-InlA monoclonal antibodies for immunostaining L. monocytogenes was also demonstrated.

The influence of antibody structural format and chip surface chemistry on assay sensitivity. Biosens Bioelectron 2006; 22:268-74. [PMID: 16487701 DOI: 10.1016/j.bios.2006.01.010] [Citation(s) in RCA: 36] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2005] [Revised: 01/05/2006] [Accepted: 01/09/2006] [Indexed: 11/28/2022]
Abstract
BACKGROUND Recombinant antibody fragments are valuable tools for SPR-based detection of small molecules such as illicit drugs. However, the multiple structural formats of recombinant antibody fragments are largely uncharacterised with respect to their respective performance in SPR sensing. We have expressed a model anti-M3G antibody in both scFv and chimeric Fab formats to examine its sensitivity and binding profiles in a microplate immunoassay format and Biacore. We have further examined the influence of scFv multimerisation, Fab constant region stability and SPR chip surface coating chemistry, on anti-hapten SPR assay development. RESULTS Under optimised competition ELISA conditions, the anti-M3G scFv was found to have an IC(50) value of 30 ng/ml, while the most stable Fab construct exhibited an IC(50) value of 2.4 ng/ml. In SPR competition assay on an M3G-OVA-coated SPR chip surface, the two constructs again differed in sensitivity, with IC(50) values of 117 and 19 ng/ml for the scFv and Fab, respectively (the scFv also exhibiting poor linearity of response). However, when the SPR chip surface was directly coated with M3G, both antibody constructs exhibited good linearity of response, similar high sensitivity IC(50) values (scFv 30 ng/ml, Fab 14 ng/ml) and high reproducibility (50 effective regenerations for M3G-OVA, 200 for M3G direct). During SPR assay development it was noticed that scFv and Fab constructs gave differing off-rate profiles. Subsequent HPLC, ELISA and electrophoretic analyses then confirmed that a portion of the scFv population multimerises. Bivalent scFv was found to profoundly affect the dissociation curve for scFv in stringent SPR kinetic analyses, leading to a 40-fold difference in calculated off-rate values (Fab off rate 4.7 x 10(-3)S(-1), scFv off rate 1.03 x 10(-2)S(-1)). CONCLUSION The structural format of recombinant antibody fragments and chip functionalisation methodology can both profoundly affect the function of anti-M3G SPR assay, with direct coating and Fab format proving to be optimal. The confirmation of scFv multimerisation and resulting changes in SPR kinetics profile, in comparison with a Fab, further suggest that caution must be taken in the interpretation of SPR sensorgrams, which are commonly used in the 'affinity ranking' of scFv panels in which the extent of dimerisation in each sample is unknown.

Abstract
In the year 2003 there was a 17% increase in the number of publications citing work performed using optical biosensor technology compared with the previous year. We collated the 962 total papers for 2003, identified the geographical regions where the work was performed, highlighted the instrument types on which it was carried out, and segregated the papers by biological system. In this overview, we spotlight 13 papers that should be on everyone's 'must read' list for 2003 and provide examples of how to identify and interpret high-quality biosensor data. Although we still find that the literature is replete with poorly performed experiments, over-interpreted results and a general lack of understanding of data analysis, we are optimistic that these shortcomings will be addressed as biosensor technology continues to mature.
