SDF 1a Mouse

Stromal Cell-Derived Factor-1 Alpha Mouse Recombinant (CXCL12)

Stromal Cell-Derived Factor-1 alpha Mouse Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 68 amino acids and having a molecular mass of 7921 Dalton.
The SDF-1a is purified by proprietary chromatographic techniques.

Accession

P40224

Amino acid sequence

The sequence of the first five N-terminal amino acids was determined and was found to be Lys-Pro-Val-Ser-Leu.

Biological Activity

The specific activity as determined by its ability to chemoattract human peripheral blood monocytes at 50-100ng/ml corresponding to a Specific Activity of 10,000-20,000IU/mg.

Formulation

The CXCL12 protein was lyophilized from a concentrated (1 mg/ml) sterile solution containing 10mM acetic acid (AcOH).

Physical Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

Greater than 98.0% as determined by:
(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility

It is recommended to reconstitute the lyophilized Stromal Cell-Derived Factor-1a in sterile 18MΩ-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Source

Escherichia Coli.

Stability

Lyophilized SDF-1a 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.
