Chromogenic Substrates
Chromogenic substrates are compounds that produce a visible color change when acted upon by specific enzymes. These substrates are widely used in diagnostic assays, biochemical research, and enzyme-linked immunosorbent assays (ELISAs) to detect and quantify enzyme activity. The color change allows for easy and rapid visual identification of enzyme reactions, making chromogenic substrates essential tools in laboratory analysis. At CymitQuimica, we provide a diverse selection of high-quality chromogenic substrates to support your research and diagnostic applications.
