Stability of T-2, HT-2, and T-2 tetraol in biological fluids.
The stabilities of tritium-labeled T-2, HT-2, and T-2 tetraol were studied in blood and urine at -70 degrees, 4 degrees, and 23 degrees C for 6 months in the presence of EDTA or NaF. Samples were counted with a radiochromatographic scanner and results indicated the stability of T-2 tetraol greater than T-2 greater than HT-2. Toxins were most stable when stored at -70 degrees C, in the presence ...
متن کاملProduction of antibody against T-2 toxin.
Antibody against T-2 toxin was obtained after immunization of rabbits with bovine serum albumin-T-2 hemisuccinate conjugate. The antibody had greatest binding efficiency for T-2 toxin, less efficiency for HT-2, and least for T-2 triol. Cross-reaction of antibody with neosolaniol, T-2 tetraol, and 8-acetyl-neosolaniol was very weak. Diacetoxyscirpenol, trichodermin, vomitoxin, and verrucarin A e...
متن کاملPreparation and characterization of the deepoxy trichothecenes: deepoxy HT-2, deepoxy T-2 triol, deepoxy T-2 tetraol, deepoxy 15-monoacetoxyscirpenol, and deepoxy scirpentriol.
The production of deepoxy metabolites of the trichothecene mycotoxins T-2 toxin and diacetoxyscirpenol, including deepoxy HT-2 (DE HT-2), deepoxy T-2 triol, deepoxy T-2 tetraol, deepoxy 15-monoacetoxyscirpenol, and deepoxy scirpentriol is described. The metabolites were prepared by in vitro fermentation with bovine rumen microorganisms under anaerobic conditions and purified by normal and rever...
متن کاملAssay and relationship of HT-2 toxin and T-2 toxin formation in liquid culture.
Both T-2 toxin and HT-2 toxin can be conveniently quantitated in crude extracts by using a combination of thin-layer chromatography and fluorodensitometry. This technique was used to follow the production of these toxins by liquid cultures of Fusarium poae (NRRL 3287). T-2 toxin was produced prior to HT-2 toxin and hexadeuterio-T-2 toxin was converted by the culture to trideuterio-HT-2 toxin.
متن کاملMetabolism of HT-2 Toxin and T-2 Toxin in Oats
The Fusarium mycotoxins HT-2 toxin (HT2) and T-2 toxin (T2) are frequent contaminants in oats. These toxins, but also their plant metabolites, may contribute to toxicological effects. This work describes the use of 13C-assisted liquid chromatography-high-resolution mass spectrometry for the first comprehensive study on the biotransformation of HT2 and T2 in oats. Using this approach, 16 HT2 and...
