摘要
Antibody against aflatoxin G1 (AFG1) was obtained from rabbits after immunizing the animals with AFG1 hemiacetal (AFG2a) conjugated to bovine serum albumin. A direct heterogenous ELISA in which AFG2a was conjugated to horseradish peroxidase was used for monitoring the antibody titers and for toxin detection. Competitive ELISA assay revealed that the antibody was most specific for AFG2a and least for AFB2. The relative cross-reactivity of this antiserum with aflatoxins G2a, G2, G1, M1, B1 and B2 was found to be 1, 7, 13, 47, 48, and 63, respectively. The lower detection limits for detection of AFG1 after derivatizing to AFG2a was around 15-25 pg per assay.
