INTRODUCTION
Streptavidin is a tetrameric protein secreted by Streptomyces avidinii which binds firmly to biotin. Streptavidin is widely used in molecular biology through its unique high affinity for the vitamin biotin. The dissociation constant (Kd) of the biotinstreptavidin complex is about ~1015mol/L. The strong affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits. The streptavidin/biotin system has one of the biggest free energies of association of yet observed for noncovalent binding of a protein and small ligand in aqueous solution (K_assoc = 1014). The complexes are also extremely stable over a wide range of temperature and pH.
DESCRIPTION
StreptavidinStreptomyces AvidiniiRecombinant produced in E.Coli. The molecular weight per tetramer is approximately 52kDa.
SOURCE
Escherichia Coli.
PHYSICAL APPEARANCE
Sterile Filtered White lyophilized (freezedried) powder.
FORMULATION
Lyophilized in 10mM potassium phosphate buffer pH 6.5.
SOLUBILITY
It is recommended to reconstitute the lyophilized Streptavidin in sterile 18MΩ-cm H2O not less than 0.5 mg/ml, which can then be further diluted to other aqueous solutions.
STABILITY
Streptavidin is shipped at ambient temperature, upon arrival store at 20 ℃.
PURITY
Greater than 98.0% as determined by SDS-PAGE and HPLC.
SPECIFIC ACTIVITY
17U/mg (one unit binds 1 μg Dbiotin at pH 8.9).
PROTEOLYTIC ACTIVITY
10 U/mg protein (25 °C, 24 h, pH 8.0).
