Development of a specific monoclonal antibody-based icELISA for detection of arecoline in traditional Chinese medicines and fresh areca nuts
ABSTRACT Arecoline, the dominant alkaloid existing in areca nuts, is an addictive substance and classified as a Group 2B potential human carcinogen. Currently, the detection of arecoline is mostly dependent on chromatography-based approaches, which are time-consuming and expensive. We used arecaidine as a hapten to produce a highly specific monoclonal antibody (mAb) against arecoline. An indirect competitive enzyme-linked immunosorbent assay (icELISA) was developed using the mAb-A5H12, to detect arecoline in traditional Chinese medicines and fresh areca nuts. The icELISA indicated that the half maximum inhibition concentration (IC50) for arecoline was 67.9 ng/mL, with a working range of 10.1–502.6 ng/mL and a limit of detection (LOD) of 3.6 ng/mL. High-performance liquid chromatographic (HPLC) confirmed the accuracy and the working range of icELISA, suggesting that the icELISA approach based on the arecoline specific antibody could be a widely applicable and easy operation method in detection of arecoline in foods and medicines.
期刊介绍：
Food and Agricultural Immunology is an international open access journal publishing original immunological research with applications in food, agricultural, environmental and veterinary science. Submissions describing the use of immunological techniques and methods are particularly welcomed.
The journal aims to expand our understanding of the interactions at the interface of food and immune systems including studies on:
-Development of diagnostic systems – all types of ligand-based assays, e.g. antibody, aptamer
-Application of ligand-based assays for the detection or identification of molecules of interest in food science, agricultural research, veterinary investigations and clinical systems relating to food allergy or sensitivity to agricultural chemicals
-Effects of food on the immune system
-Studies on allergy and allergic reactions
-Investigations into food allergies
-Development of allergen-free food systems
-Development of novel assay formats
-Applications of assay systems to the monitoring of food items in relation to safety and labelling
-Food quality issues, e.g. speciation, adulteration and contamination
-Comparisons between different analytical techniques
The journal publishes research and review articles and is essential reading for food scientists, immunologists and all those concerned with the interaction between food and immune systems.
