Technology
Veratox for Chloramphenicol is an enzyme-linked immunosorbent assay (ELISA). The basis of this test is a competition between a chloramphenicol-enzyme conjugate and any free chloramphenicol from the sample for a limited number of binding sites on the antibody-coated microplate wells.
Samples are extracted, and the extracts (and solutions of chloramphenicol standards) are added to the microplate wells. A solution of the chloramphenicol-enzyme conjugate is also added to each of the wells. At this point, time is allowed for any free chloramphenicol and the chloramphenicol-enzyme conjugate to compete for the binding sites on the plate. Next, the plate is washed to remove unbound material and a substrate solution is added to each well. During an ensuing reaction period, any bound enzyme conjugate reacts with the substrate to produce a blue-colored solution. The color-forming reaction is terminated by adding Stop Solution to the wells of the plate, turning the blue color to yellow. The absorbance of each well is then measured using a microplate reader set at 450 nm. The extent of color formation is inversely proportional to the amount of chloramphenicol present in that well.
Samples that contain little or no chloramphenicol will have a relatively large absorbance while a sample that contains more chloramphenicol will have a smaller absorbance. Quantitative results may be obtained by comparing the absorbance of the samples to a standard curve generated from the wells containing the chloramphenicol standards.
