Streptavidin is a tetrameric protein from Streptomyces avidinii that binds very tightly to the vitamin biotin with a Kd of ≈10-14 mol/L. The high-affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits.

GenScript Streptavidin Antibody is developed in rabbit using purified Streptavidin and highly purified from rabbit antiserum by protein G resin.
Ig Subclass
Rabbit IgG
The antibody is stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C. For long term storage, aliquot and store at -20°C or below. Avoid repeated freezing and thawing cycles.
GenScript Streptavidin Antibody is specific to streptavidin.
5 mg/ml, lyophilized in PBS, pH7.4, containing 0.02% sodium azide
Purified recombinant streptavidin
Purification Method
Protein G chromatography
Reconstitute the lyophilized antibody with deionized water (or equivalent) to a final concentration of 5.0 mg/ml.
Working concentrations for specific applications should be determined by the investigator. The appropriate concentrations may be affected by secondary antibody affinity, antigen concentration, the sensitivity of the method of detection, temperature, the length of the incubations, and other factors. The suitability of this antibody for applications other than those listed below has not been determined. The following concentration ranges are recommended starting points for this product.
ELISA: 0.5-1 ug/ml
Dot blot: 0.5-1 ug/ml
Western blot: 0.5-1 ug/ml
Other applications: user-optimized
Briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container's cap because small volumes of antibody will occasionally become entrapped in the seal of the product vial during shipment and storage.
