[Preparation of antibodies to roridin A and their applications].


PMID 10994191

Abstract

Polyclonal rabbit antibodies against a conjugate synthesized through condensing BSA and disubstituted roridin A hemisuccinate allowed roridin A to be determined in solutions at a sensitivity of 0.2 ng/ml. The cross-reactivity of structural analogues--roridin A, verrucarin, and verrucarol--amounted to 100, 2.5, and 0.03%, respectively. The data showed that these antibodies determine roridin A in an indirect heterogeneous enzyme immunoassay in cereal straw samples at a sensitivity of 20 micrograms/kg.
