Streptavidin is a 66KDa 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 44KDa 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.
特徴
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 18.6 kDa.
The protein migrates as 19-20 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
