For this purpose, a specific anti-ZEN monoclonal antibody (mAb), 4A3-F9, was obtained and identified. ZEN coupled to bovine serum albumin (BSA) via 1,4-butanediol diglycidyl ether was prepared as immunogen. The mAb showed low crossreactivity with five ZEN analogues. Using an antibody preparation with a titer of ≥1:5.12 × 105, the cross-reactivity (CR) of the anti-ZEN monoclonal antibody with four of the analogues was
