---

Amino acid sequence
KPVSLSYRCP CRFFESHVAR ANVKHLKILN TPNCALQIVA RLKNNNRQVC IDPKLKWIQE YLEKALNKRF KM.

Biological Activity
The specific activity as determined by its ability to chemoattract human peripheral T cells stimulated with IL-2 and PHA in a concentration range from 10-75 ng/ml corresponding to a Specific Activity of 13,334-100,000IU/mg.

Description
Stromal Cell-Derived Factor-1 beta Feline Recombinant produced in E.Coli is a non-glycosylated, Polypeptide chain containing 72 amino acids and having a molecular mass of 8526 Dalton.
The SDF-1b is purified by proprietary chromatographic techniques.

The 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 97.0% as determined by(a) Analysis by RP-HPLC.
(b) Analysis by SDS-PAGE.

Solubility
It is recommended to reconstitute the lyophilized SDF-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.
