Synonyms

Streptavidin, SA

Source

Streptavidin is expressed from E. coli cells and conjugated with alkaline phosphatase under optimal conditions.

Molecular Characterization

This protein carries no "tag".

The protein has a calculated MW of 13.8 kDa.

Application

Recommended for use in ALP Chemiluminescence System such as CLEIA (0.1 µg/mL) or MPCLIA, immunohistochemistry, and western blot applications. Avoid using biotin-containing solutions as diluents. It is recommended that the reagent be titrated for optimal performance for each application. 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.
