Bioassay in toxicology
A bioassay is an analytical method to determine the concentration or potency of a substance by its effect on living animals or plants (in vivo), or on living cells or tissues(in vitro). A bioassay can be either quantal or quantitative, direct or indirect. If the measured response is binary, the assay is quantal, if not, it is quantitative. WebBioassays have become increasingly useful for mycotoxin detection as a precursor to chemical analysis. Bioassay by biosensor is designed as an inhibition assay. In these methods, a fixed concentration of mycotoxin-specific antibody is mixed with a sample containing an unknown amount of mycotoxin. The antibody and mycotoxin form a complex.
