Quantitative Assessment of Bony Fish Tropomyosin Using a Monoclonal Antibody Competitive ELISA.

Bony fish is one of the big-nine allergenic foods in the US. This study established a monoclonal antibody (mAb)-based indirect competitive enzyme-linked immunosorbent assay (ELISA) for the detection of bony fish tropomyosin (TM), a fish allergen. Immunoassay (Western blot and ELISA) was performed to characterize anti-TM mAb8F5 (target configuration, immunoaffinity, and species selectivity).
