Biological Activity
Full biological activity determined by a chemotaxis bioassay using PHA and rHuIL-2 activated human peripheral blood T-lymphocytes is in a concentration range of 20-80 ng/mL.

Appearance
Lyophilized powder.

Formulation
Lyophilized after extensive dialysis against 20 mM PB pH 7.0, 130 mM NaCl.

Endotoxin Level
<1 EU/μg, determined by LAL method.

Reconstitution
Reconstitute the lyophilized recombinant Human Stromal-Cell Derived Factor-1 alpha/CXCL12 (rHuSDF-1α/CXCL12) to 0.1-1.0 mg/mL using sterile distilled water or aqueous buffer containing 0.1% BSA.

Storage & Stability
Lyophilized recombinant Human Stromal-Cell Derived Factor-1 alpha/CXCL12 (rHuSDF-1α/CXCL12) is stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Shipping
Room temperature in continental US; may vary elsewhere.

Background
CXCL12 belongs to the CXC chemokine family, and is expressed in two isoforms, SDF-1α and SDF-1β, binds to CXCR4 and CXCR7. CXCL12/CXCR4 signal is implicated in tumor proliferation, survival, vascularization, metastasis, and immunosuppression[1].
