Streptavidin Protein-HRP, Horseradish peroxidase conjugated Streptavidin
Streptavidin is expressed from E. coli cells and conjugated with horseradish peroxidase under optimal conditions.
Product Specifications
Background
Streptavidin is a 66 kDa tetrameric protein purified from the bacterium Streptomyces avidinii, and exhibits high binding affinity to biotin. Each unit can bind one biotin. Horseradish peroxidase is metalloenzyme, a 44 kDa glycoprotein. When incubate with substrates, it produces a coloured, fluorimetric, or luminescent derivatives, which can be detected and quantified. HRP conjugated Streptavidin is widely used for the detection and quantification of biotinylated proteins.
Specifications
This protein carries no "tag". The protein has a calculated MW of 13.4 kDa.

Applications
NOTE: Do not use skim milk as a blocking agent in the assay with streptavidin, since skim milk contains free biotin which will cause high backgrounds.
