title: Production and characterization of antibody against deoxyverrucarol.
abstract: Immunization of rabbits with deoxyverrucarol (DOVE) conjugated to bovine serum albumin resulted in antibodies bound with either tritiated DOVE or diacetoxyscirpenol (DAS), but not with T-2 toxin. The affinity of antibodies with DOVE was found to be much higher than with DAS. When [3H] DOVE was used as a marking ligand in the competitive radioimmunoassay, the concentrations causing 50% inhibition of binding radioactivities by unlabeled DOVE, verrucarol, verrucarin A, and 4-monoacetoxyscirpenol were found to be 0.32, 1,070, 9,500, and 10,000 ng per assay, respectively. T-2 toxin, 15-monoacetoxyscirpenol, and deoxynivalenol gave less than 20% inhibition at 10 micrograms per assay. However, when [3H] DAS was used as the marking ligand, the concentrations causing 50% inhibition by DOVE, DAS, and verrucarol were found to be in the 50 to 60 ng per assay range. The antibodies are thus highly specific to DOVE rather than a common trichothecene backbone. The possible use of this antiserum for assay of macrocyclic trichothecenes is discussed.
