ABTS? Solution is a ready to use substrate for peroxidase-driven indicator reactions. It contains 2,2-azino-di-[3-ethylbenzthiazoline sulfonate (6)] and H2O2 in glycin/citric acid buffer and is available in slightly green color.
2,2′-azino-di-(3-ethylbenzthiazoline sulfonic acid) or ABTS? acts a substrate for HRP (horseradish peroxidase) conjugate during enzyme-linked immunosorbent assay (ELISA). It is the most sensitive, and stable substrate when compared to three other substrates namely, 5-aminosalicylic acid (5AS), O-phenylenediamine (OPD), O-tolidine (OT). It also produces the best visual results, where it gives a bluish-green color. ELISA using ABTS? is a highly sensitive, specific and reproducible technique This solution is an excellent substrate for enzyme immunoassays with horseradish peroxidase as a marker enzyme.
