Luminol is one of the most widely used chemiluminescent reagents. The oxidation of luminol by peroxide results in creation of an excited state product called 3-aminophthalate. This product decays to a lower energy state by releasing photons of light. Chemiluminescent reaction of AP substrate- CDP-Star At very low horseradish peroxidase (HRP) concentrations, the enhanced chemiluminescence reaction is often characterized by a lag time between initiation of the reaction and beginning of light output. In this study, four treatments of luminol solution were examined in an effort to remove the lag time and to improve chemiluminescence light output The horseradish peroxidase (HRP) 1-catalyzed chemiluminescent oxidation of luminol is widely used in many molecular biology-based assays, such as Western blots, dot blots, and enzyme-linked immunosorbent assays (ELISAs), as well as in immunohistochemistry.Much effort has been made to improve the efficiency and analytical performance of this reaction Chemolumineszenzreaktion von Luminol. Bei der Chemolumineszenz-Reaktion handelt es sich bei Luminol als Ausgangsstoff um eine Dicarbonylverbindung, ein so genanntes 1,4- Dion.

Conditions for the enhanced horseradish peroxidase (HRP) catalysed reaction between luminol and hydrogen peroxide were optimized to determine detection limits for HRP conjugated to antibody. INTRODUCTION The enhanced chemiluminescence of the luminol- H2O2-horseradish peroxidase system has received great attention in recent years. Since 1983, when enhancement by firefly luciferin was described (1), numerous new intensifiers of the luminol-H2O2- horseradish peroxidase system have been discovered Numerous phenol derivatives enhance luminol- H2O2-horseradish peroxidase chemiluminescence (7-12). The spectra of the unenhanced and enhanced chemiluminescence are similar (7,8). This is because the chemiluminescent emission is from aminophtha- late, which emits around 425 nm, and the enhancers simply accelerate the reaction Horse Radish Peroxidase (HRP) is heme-containing protein isolated from wild horse radish roots.HRP catalyzes the transfer of two electrons from a substrate to hydrogen peroxide (H2O2), to generate.. Many phenolic compounds are known to enhance the chemiluminescence associated with the horseradish peroxidase-catalyzed oxidation of luminol, but the mechanism of enhancement is still unproved

Horseradish peroxidase - Wikipedi

Horseradish peroxidase (HRP) is an enzyme used to amplify signal in photometric assays by catalyzing the conversion of chromogenic or chemiluminescent substrates for the detection of targets such as proteins, carbohydrates, and nucleic acids. HRP is typically conjugated to an antibody, protein A, protein G, or avidin, although HRP can readily be conjugated to a wide range of different types of. As the precise mechanism of the HRP-catalyzed chemiluminescent oxidation of luminol in the presence of a p-phenol derivative has not been 100% proved. However, phenoxyl radical generation was the main factor to affect the HRP-catalyzed chemiluminescent oxidation of luminol
