Abstract

An artificial antigen of aflatoxin biosynthetic precursor Sterigmatocystin (ST) and a method for preparing same. Firstly, hydroxyacetic acid is reacted with the double bound of the difuran ring in the aflatoxin biosynthetic precursor ST, yielding an aflatoxin biosynthetic precursor ST hapten with an active carboxymethoxy group. Secondly, a carboxyl group on the ST hapten is attached to an amino group on a carrier protein. At last, the artificial antigen of aflatoxin biosynthetic precursor ST is obtained by dialysis and lyophilize.
