What is avidin HRP?
Avidin is conjugated with horseradish peroxidase under optimal conditions. Avidin-HRP is useful as a second step reagent for indirect enzymatic labelling, in conjunction with biotinylated primary antibodies. Av-HRP is recommended for ELISA, ELISPOT and Western blotting, when used with the relevant substrate system.
What is streptavidin HRP used for?
Streptavidin-HRP is useful for detecting biotinylated antibodies, e.g., in ELISA, ELISPOT, IHC or Western blotting. For ELISA applications, HRP will act on soluble substrates, such as ABTS or TMB, to yield a colorimetric reaction.
What is HRP substrate?
Horseradish peroxidase (HRP) substrates are used in the immunostaining and immunodetection of specific proteins and antigens. HRP is a widely used label, often conjugated to secondary antibodies in immunochemical applications such as immunohistochemistry, western blotting, and ELISA.
What is Streptavidin HRP?
HRP-Conjugated Streptavidin consists of streptavidin protein that is covalently conjugated to horseradish peroxidase (HRP) enzyme (RZ > 3.0). Streptavidin binds to biotin and the conjugated HRP provides enzyme activity for detection using an appropriate substrate system.
Is streptavidin HRP light sensitive?
Yes HRP is light sensitive. It is important to avoid excessive exposure to light, Therefore using dark moisture chember is very useful during these steps.
What is peroxidase used for?
Peroxidase is an enzyme found in a wide variety of organisms, from plants to humans to bacteria. Its function is to break down hydrogen peroxide (H2O2), which is one of the toxins produced as a byproduct of using oxygen for respiration.
How does HRP staining work?
Horseradish peroxidase (HRP) is a 44-kDa protein that catalyzes the oxidation of substrates in the presence of hydrogen peroxide, resulting in a colored product or the release of light as one product of the reaction (chemiluminescence).
