Product Name: Stromal Cell Derived Factor-1 Beta Mouse Recombinant (CXCL12)
Synonyms: SDF-1, CXCL12, Pre-B cell growth-stimulating factor, PBSF, hIRH, chemokine (C-X-C motif) ligand 12, SDF1, SDF1B, TPAR1, SCYB12, SDF-1b, TLSF-b, 12-O-tetradecanoylphorbol 13-acetate repressed protein 1, Thymic lymphoma cell-stimulating factor, TLSF.
Description: Stromal Cell-Derived Factor-1 beta Mouse Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 72 amino acids and having a molecular mass of 8513 Dalton. The SDF-1b is purified by proprietary chromatographic techniques.
Uniprot Accesion Number: 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.
Source: Escherichia Coli.
Physical Appearance and Stability: Lyophilized SDF-1b although stable at room temperature for 3 weeks, should be stored desiccated below -18C. Upon reconstitution CXCL12 should be stored at 4C between 2-7 days and for future use below -18C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.
Formulation and Purity: The CXCL12 protein was lyophilized from a concentrated (1mg/ml) sterile solution containing no additives. Greater than 98.0% as determined by:(a) Analysis by RP-HPLC.(b) Analysis by SDS-PAGE.
Application:
Solubility: It is recommended to reconstitute the lyophilized Stromal Cell-Derived Factor-1b in sterile 18MO-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Biological Activity: The specific activity as determined by its ability to chemoattract human monocytes at 50-100ng/ml corresponding to a Specific Activity of 10, 000-20, 000IU/mg.
Shipping Format and Condition: Lyophilized powder at room temperature.
