Chromogenic substrate solution
WebChromogenic Assay The most common type of ELISA detection uses a colorimetric assay. Generally, horseradish peroxidase (HRP-) or alkaline phosphatase (AP-) conjugated … WebChromogens/substrates used in chromogenic IHC are acted on by the reporter enzyme to form a colored precipitate. The choice of chromogen used is directed by the enzyme employed in the experiment, as well as a number of other factors. Here, we review guidelines for selecting the appropriate enzyme substrate for chromogenic detection.

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. WebThe chromogenic substrates used in this test are various sugars that are linked to either o-nitrophenol or p-nitrophenol by a glycosidic bond. Hydrolysis of the bond frees the …
