Veratox for Chloramphenicol is an ELISA for the quantitative analysis of chloram¬phenicol residues in shrimp. This test kit operates on the basis of competition between a chloramphenicol enzyme conjugate and the chloramphenicol in the extracted sample for a limited number of binding sites on the antibody-coated plate. The test format is a 96-well plate, permitting up to 90 tests to be run at a time.
