Description: Steptavidin, a bacterial protein isolated from Streptomyces avidinii, is similar to egg-white avidin in its ability to bind biotin, and has been used as a replacement for egg-white avidin because of its more favorable chemical properties. Conjugates of streptavidin are recommended for use with Biotin-SP-conjugated antibodies and Biotin-SP-conjugated ChromPure proteins.
Streptavidin conjugated to Alkaline Phosphatase.
ELISA:- 1-2 µg / ml Western Blot:- 0.1-1 µg / ml Histo-/Cyto-Chemistry:- 1-2 µg / ml Dilution factors are presented in the form of a range because the optimal dilution is a function of many factors, such as antigen density, permeability, etc. The actual dilution used must be determined empirically.
Storage: Store at 2-8°C. Prepare working dilution on day of use. Product is stable for about 6 weeks at 2-8°C as an undiluted liquid. Extended storage: Add an equal volume of glycerol (ACS grade or better) for a final concentration of 50%, and store at -20°C as a liquid. Expiration date: one year from the date of receipt.
