Background

Streptavidin is isolated from bacteria, Streptomyces avidinii, and has an exceptionally high binding affinity for B7 (biotin). Rockland offers streptavidin in unconjugated and conjugated forms for common immunoassays including ELISA, western blotting, immunohistochemistry. Streptavidin is a tetrameric protein capable of binding 4 biotin groups to each molecule of streptavidin. While streptavidin has identical binding properties as avidin, it lacks the glycoprotein portion of the molecule and therefore shows less non-specific binding. Streptavidin is a slightly smaller molecule with a molecular weight of approximately 53.6 kDa. The sequence of avidin only shows 30% homology with streptavidin, and anti-avidin and anti-streptavidin antibodies are not immunologically cross reactive. Horseradish Peroxidase (HRP) is an enzyme that utilize organic peroxide compounds as electron donors. Naturally provides protection for plants against pathogens, but can be utilized in molecular biology to convert various substrates to detectable compounds (such as in Western Blotting and ELISAs).

Product Details

Streptavidin Peroxidase Conjugated - S000-03
HRP-SA, Horseradish Peroxidase conjugated S avidin, Streptavidin HRP, Streptavidin conjugated to horseradish peroxidase (HRP), HRP-linked Streptavidin
Peroxidase (HRP)

Target Details

Streptavidin-HRP was prepared from chromatographically purified streptavidin.  Streptavidin Peroxidase conjugate was assayed by immunoelectrophoresis resulted in a single precipitin arc against anti-Peroxidase and anti-Streptavidin.

Application Details

Dot Blot, WB
ELISA, EM, IF, IHC  - View References
Streptavidin Peroxidase has been tested by dot blot and western blot and is a useful detection reagent for primary antibodies conjugated to biotin. Streptavidin Peroxidase can be utilized in Immunohistochemistry, Immunofluorescence, immuno-EM, Western Blotting, and ELISA experiment formats in combination with the proper substrate (TMB-1000 or FEMTOMAX-110).
