Six monoclonal antibodies (mAbs, T-2.1, 2, 3, 4, 5, 6) which react with a trichothecene mycotoxin, T-2 toxin (T-2), were prepared. All antibodies specifically reacted with T-2 but less (0.5% of T-2) with the metabolites such as HT-2 toxin and 3'-hydroxy-T-2 toxin. Significant but less than 0.02% cross-reactivity was observed with T-2 triol, 3'-hydroxy-HT-2 toxin and neosolaniol. No significant reaction with other trichothecenes such as deoxynivalenol, nivalenol, fusarenon-X, crotocin, or roridin A was observed. The least detectable amount of T-2 with the best mAb T-2.1 was 2.5 pg T-2 per assay. This specific and highly sensitive assay for T-2 was applied for the quantitation of T-2 in wheat flour spiked with mycotoxin, with combination of a simple extraction procedure.

D008807 Mice, Inbred BALB C An inbred strain of mouse that is widely used in IMMUNOLOGY studies and cancer research. BALB C Mice, Inbred,BALB C Mouse, Inbred,Inbred BALB C Mice,Inbred BALB C Mouse,Mice, BALB C,Mouse, BALB C,Mouse, Inbred BALB C,BALB C Mice,BALB C Mouse
D004797 Enzyme-Linked Immunosorbent Assay An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.
