SDF 1b Feline

Stromal Cell-Derived Factor-1 beta Feline Recombinant (CXCL12)

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.

Accession

O62657

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.

Formulation

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 18MΩ-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 -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.
