Product Details

Recombinant Streptavidin is a tetrameric protein (4 x 13 kDa), which binds very tightly to the small molecule Biotin. The native Streptavidin comes from the bacterium Streptomyces avidinii and can bind 4 mol of biotin per mol of Streptavidin with a very high affinity (K d~10-15). This turns the Streptavidin/Biotin system into a valuable tool for many biochemical applications.

Streptavidin coating of solid phases offers a universal immobilization principle for the detection and analysis of proteins, peptides, PCR-fragments, haptens etc with very low non-specific binding.
