Hrp luminol reaction

Web2. Mechanism of the enhanced HRP–luminol CL system. HRP–luminol CL reaction was performed as follows: luminol catalyzed to the ground state by HRP and an enhancer in alkaline and oxidant condition was accompanied by light quantum emission. The mechanism of HRP–luminol-based CL reaction is shown in Figure 1. HRP is often used in conjugates (molecules that have been joined genetically or chemically) to determine the presence of a molecular target. For example, an antibody conjugated to HRP may be used to detect a small amount of a specific protein in a western blot. Meer weergeven The enzyme horseradish peroxidase (HRP), found in the roots of horseradish, is used extensively in biochemistry applications. It is a metalloenzyme with many isoforms, of which the most studied type is C. It … Meer weergeven Alone, the HRP enzyme, or conjugates thereof, is of little value; its presence must be made visible using a substrate that, when oxidized by HRP using hydrogen peroxide as … Meer weergeven Many materials have been explored to mimic natural HRP.
