The hapten was conjugated to bovine serum albumin (BSA) and ovalbumin (OVA) to form the immuno-antigens and the coating antigen, respectively. The antibody with high titer (2.56 × 10^4) was obtained after immuning rabbits. The results showed that the antibody had a high affinity to imidacloprid tested by enzyme-linked immunosorbent assay (ELISA), which IC50 and IC20 were 20.7 and 1.1 μg L^-1; and the cross reactibilities to those compounds related with imidacloprid were less than 1.4%.展开更多
