Comments2,2-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.
