| Stromal Cell Derived Factor-1 Beta Mouse Recombinant (CXCL12), SDF 1b Mouse, 10ug |
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.
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 monocytes at 50-100ng/ml corresponding to a Specific Activity of 10,000-20,000IU/mg.
The CXCL12 protein was lyophilized from a concentrated (1 mg/ml) sterile solution containing no additives.
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-1b in sterile 18M¦¸-cm H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Source
Escherichia Coli.
Stability
Lyophilized SDF-1b 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.
