Description
Stromal Cell-Derived Factor-1 alpha Human Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 78 amino acids, having a molecular mass of 9.2 kDa.
The SDF-1a is fused to 10 amino acids His-Tag at N-terminus and purified by proprietary chromatographic techniques.

Formulation
The protein was filtered (0.4?m) and lyophilized from a concentrated (0.5mg/ml) solution containing 20mM Tris buffer pH-7.5 and 20mM sodium chloride.

White lyophilized (freeze-dried) powder.

Purity
Greater than 95.0% as determined SDS-PAGE.

Solubility
It is recommended to add deionized water to a working concentration approximately 0.5 mg/ml and let the lyophilized pellet dissolve completely. Product is not sterile! Please filter the product by appropriate sterile filter before using it in the cell culture.

Source
Escherichia Coli.

Stability
Lyophilized SDF1A although stable at room temperature for 3 weeks, should be stored desiccated below -18¡ãC. Upon reconstitution CXCL12 should be stored at 4¡ãC between 2-7 days and for future use below -18¡ãC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
