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.
Is streptavidin HRP sensitive to light?
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.
How do you make HRTA streptavidin?
Wash membrane-bound HRP (antibody conjugate) three times for 5 minutes in TBST. Prepare 1X SignalFire™ ECL Reagent (#6883) by diluting one part 2X Reagent A and one part 2X Reagent B (e.g. for 10 ml, add 5 ml Reagent A and 5 ml Reagent B). Mix well.
What are HRP conjugated antibodies?
Horseradish peroxidase (HRP) is a 44 kDa glycoprotein with 6 lysine residues, which can be conjugated to antibodies and proteins for use in a variety of applications. The enzyme label can be visualized through chromogenic reactions. Antibody-HRP conjugates are commonly used in ELISA, IHC, and western blotting.
What is streptavidin HRP conjugate?
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.
What is streptavidin HRP?
Streptavidin HRP conjugate is a recombinant protein purified from E. coli. It is supplied as a purified product conjugated to the enzyme horseradish peroxidase (HRP). This reagent may be used as a detection reagent for biotin-conjugated primary antibodies for immunoassay applications.
What is peroxidase conjugate?
Additional Information. Thermo Scientific Pierce Peroxidase Conjugate Stabilizer is an antifreeze solution for storing freezer aliquots and stocks of antibodies and other HRP-conjugates in liquid form so they can be pipetted for use without thawing.
Which substrate is used in Elisa?
