| Abstract: | A monoclonal antibody (mAb) has been produced to aflatoxin B1 (AF B1) after successful immunization of mice and fusion of sensitized spleen cells with myeloma cancer cells. The mice were immunized with AF B1-oxime-protein conjugate. Positive mAbs were screened using an indirect ELISA specific for AF B1. The selected mAb was then developed in direct competitive ELISA and immunoaffinity column chromatography methods for aflatoxin detection in foods and feeds. Both assays are rapid, sensitive, specific and require only the minimum of sample preparation. Both immunological assays have now been commercialized and are produced in convenient ready-made kit formats. |
