Posted at 19:36h in case-mate tough groove iphone 13 by whitney houston grammy awards. The most frequent way to test for mycotoxins by immunoassay is by using a direct competitive ELISA. Immunoassay: An immunoassay is a biochemical test that measures the concentration of a substance in a biological liquid, typically serum or urine, using the reaction of an antibody or antibodies to its antigen. These techniques resulted in dramatic shortening of the time required for developing of immunoassay methods (26, 27). Immunoassays offer a number of advantages in food contaminant analysis over the conventional methods, such as HPLC and GC. Increased sensitivity of antigen and antibody can be got by automation of these techniques.
