A dual-label time-resolved fluoroimmunoassay (TRFIA) for simultaneous quantification of aflatoxin B1 (AFB1) and ochratoxin A (OTA) is described. For this, microtitration wells were coated with AFB1-horse radish peroxidase (HRP) and OTA–bovine serum albumin. The standards and samples were loaded on the coated plates, and diluted antibodies and Eu3+- and Sm3+-labeled IgG were then added. Our results...
Using indirect competitive time-resolved fluoroimmunoassay (TRFIA), a rapid, highly selective and extremely sensitive method has been established for the determination of ochratoxin A (OA). Tests can be performed in a 96-well microplate using the toxin-specific polyclonal antibodies, obtained from rabbits immunized with ochratoxin A-keyhole limpet’s hemocyanin (OA–KLH). In indirect TRFIA format, ochratoxin...
