Description
Streptavidin Protein-Alexa Fluor 488 (STN-NA118) is expressed from E. coli cells.
Background
Streptavidin is a tetrameric protein purified from the bacterium Streptomyces avidinii, and exhibits high binding affinity for biotin. Able to bind one molecule of biotin with each subunit. Streptavidin (PI=6.0-7.5) has lower level of non-specific binding to various biological components at physiological pH than avidin (PI=7.4), resulting from its isoelectric point (PI).Streptavidin is useful in affinity chromatography, ELISA, immunohistochemistry and Western Blotting.
Molecule
Streptavidin
Characteristics
This protein carries no "tag". The protein has a calculated MW of 13.8 kDa. The protein migrates as 15 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE).
Buffer
PBS, pH 7.4
Stability
● -20°C to -70°C for 12 months in lyophilized state;
● -70°C for 3 months under sterile conditions after reconstitution._x000D_For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Protectant
trehalose
