Zearalenone is an estrogenic mycotoxin produced by the fungus Fusarium graminearum. Zearalenone induces feminization in animals at concentrations in feed of about 1 ppm. Higher concentrations (50-100 ppm) can interfere with conception, ovulation, implantation, fetal development, and the viability of newborn animals. ZearalaTest is a monoclonal antibody-based affinity chromatography method for the detection of zearalenone mycotoxin at parts per million levels. Quantitative results can be obtained using a fluorometer, LC or TLC. ZearalaTest WB is designed for the rapid, precise detection of zearalenone using wide bore immunoaffinity columns. ZearalaTest WB allows for a faster flow rate and is the ideal cleanup step for any LC or LC-MS/MS analysis. Zearala-V AQUA Strip Tests utilize monoclonal antibodies to accurately detect and measure zearalenone at levels as low as 0.1 ppm and as high as 5.0 ppm, with a solvent-free extraction procedure.
