An indirect competitive ELISA for determination of guanidine acetic acid in animal feed

Abstract To establish an indirect competitive ELISA (ci-ELISA) for the detection of guanidino acetic acid (GAA) residues in animal feed, in this study, GAA was coupled to carrier proteins via the active ester method to obtain an anti-GAA complete antigen (GAA-BSA) and a detection antigen (GAA-OVA)....
