SDF 1a Human, His

Stromal Cell-Derived Factor-1 alpha Human Recombinant, His Tag

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.

Accession

P48061

Amino acid sequence

MKHHHHHHAS KPVSLSYRCP CRFFESHVAR ANVKHLKILN TPNCALQIVA RLKNNNRQVC IDPKLKWIQE YLEKALNK.

Formulation

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

Physical Appearance

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 -18oC. Upon reconstitution CXCL12 should be stored at 4oC between 2-7 days and for future use below -18oC.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Please prevent freeze-thaw cycles.
