摘要: Abstract BACKGROUND Fumonisin B1 (FB1) is a cancer‐promoting mycotoxin produced by Fusarium species and one of the major food‐borne toxins in corn and corn products. The objective of this study was to produce a single‐chain variable fragment (scFv) antibody for determination of FB1 in corn samples. RESULTS Anti‐FB1 monoclonal antibodies were obtained via the hybridoma technique. Specific heavy‐and light‐chain variable fragments were amplified with degenerate primers and constructed into scFv antibody fragments by …
