ALERT - Histamine Screening Kit
Ex. NEOGEN - USA
Alert for Histamine is a quick screening test to detect this toxin at graded levels, including the FDA action level of 50 ppm. The test is a competitive direct enzyme-linked immunosorbent assay (CD-ELISA) that uses a quick water extraction process to extract histamine from a sample. If the sample has more blue color than the known control, it contains less histamine than the control.

VERATOX - Quantitative Histamine Kit
Ex. NEOGEN - USA
Veratox for Histamine is a CD-ELISA that allows testers to obtain exact concentrations in ppm. The test is read in a microwell reader to yield optical densities. The control optical densities of 0, 5, 10, 20 and 50 ppm are used to form the standard curve, and the sample optical densities are plotted against the curve to calculate the exact concentration of histamine.

VERATOX - Quantitative Chloramphenicol Kit
Ex. NEOGEN - USA
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.

ALERT - Sulfite Screening Kit
Ex. NEOGEN - USA
The Alert for Sulfites test kit quickly and easily detects sulfites. Sulfite residues in a sample will produce color changes in a dye reagent provided with the kit. These color changes, and the rate of the changes, are indicative of the level of sulfite residues in the sample.
