Chromogenic substrate assay
Here is the list of chemicals you would need for a chromogenic assay: 1. Substrate (chromogen) 2. Corresponding enzyme 3. Compound for primarily detecting the target You will need a substrate that can be broken down by an enzyme to produce a visible color change. This enzyme corresponds with … See more Here is an analogy to demonstrate the basic concept of a chromogenic assay. Imagine having a magic dart that always hits the target even if you throw it in the dark. Exploiting this property, you throw this dart to detect … See more In chromogenic assays the final step in detection is facilitated by a color change – due to production of a colored product compound from the chromogenic substrate. The higher … See more Any technique that involves qualitative and quantitative detection with the help of a visible color change is a chromogenic assay.
