WebABTS ELISA Peroxidase Substrate (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid)) is a chromogenic substrate use to visualize reactivity of certain enzymes, particularly in immunosorbent assays. ABTS ELISA Peroxidase Substrate is commonly used with peroxidases, but is amenable to many other enzymes. WebIn the second stage, a chromogenic substrate is added; the latter is a target for the recently activated Xa which cleaves it and releases the paranitroaniline (pNA) that can be detected optically at 405 nm. Also, in the second stage, a thrombin inhibitor is added to block any enzymatic action by thrombin on the chromogenic Xa-substrate.
