Detection of membrane-bound molecules is carried out by a variety of procedures. In protein analysis, the molecules of interest are usually detected with specific first antibodies, enzyme-labeled secondary reagents (antibody- or streptavidin-conjugates) and a suitable chromogenic substrate. These detection systems, however, may be time-consuming or lacking sensitivity. In addition, colors tend to fade with time and exposure to light.
To overcome these problems, attempts have been made to use chemiluminescence for fast and sensitive detection of enzyme conjugates on blots. The BM Chemiluminescence Western Blotting System is designed around peroxidase-labeled secondary antibodies and the substrate luminol. In the presence of hydrogen peroxide (H2O2), horseradish peroxidase (POD, HRP) catalyzes the oxidation of diacylhydrazides such as luminol. An activated intermediate reaction product is formed, which decays to the ground state by emitting light. Strong enhancement of the light emission is produced by 4-iodophenol. This acts as a radical transmitter between the formed oxygen radical and luminol.
