Product Detail: The MaxSignal Domoic Acid (ASP) ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Domoic Acid in mussels, algae and water samples. This kit is based on a competitive colorimetric ELISA assay. The second antibody against Anti-Domoic Acid Antibody was coated in the plate wells. During the analysis, sample is added along with the Domoic Acid-horseradish peroxidase conjugate (Domoic Acid-HRP Conjugate) and Anti- Domoic Acid Antibody. If the Domoic Acid residue is present in the sample, it will compete with Domoic Acid-HRP Conjugate for the Anti-Domoic Acid Antibody, thereby preventing the Domoic Acid-HRP Conjugate from binding to the Anti-Domoic Acid Antibody. The Anti-Domoic Acid Antibody is then bound by the second antibody immobilized on the plate. After a washing step and addition of the TMB substrate solution, a color signal is produced. The color reaction is stopped after a specified time and the color is evaluated using an ELISA reader. The resulting color intensity has an inverse relationship with the domoic acid residue concentration in the sample.

Domoic acid and its isomers are water-soluble neurotoxins produced by a number of marine algae, in particular by the microalgae of the genus Pseudo-nitzschia. Blooms of Pseudo-nitzschia spp. may lead to the accumulation of domoic acid in shellfish filter feeders and other marine species. Ingestion of domoic acid contaminated shellfish may cause human illness called amnesic shellfish poisoning (ASP) by affecting the central nervous system. ASP has caused the death of both animal and human consumers in severe cases. The European Commission Directive 2002/226/EC implemented a domoic acid maximum permitted level (MPL) of 20 ppm (mg/kg) in shellfish intended for human consumption. This MPL is adopted by the regulatory authorities in most other countries.
