Overview
Regulatory Status: RUO
Shipping:
Blue Ice or room temp
Storage:
The recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Background:
SDF-1α and β are stromal-derived, CXC chemokines that signal through the CXCR4 receptor. SDF-1α and β chemoattract B and T cells, and have been shown to induce migration of CD34+ stem cells. Additionally, the SDF-1 proteins exert HIV-suppressive activity in cells expressing the CXCR4 receptor. Human and murine SDF-1 proteins act across species. SDF-1α and β contain the four highly conserved cysteine residues present in CXC chemokines. The mature SDF-1α protein is the result of alternative splicing of the SDF-1 gene and contains 68 amino acid residues. Recombinant Human SDF-1α is an 8.0 kDa protein containing 68 amino acid residues.
Biological Activity:
Determined by its ability to chemoattract IL-2-activated human T cells using a concentration range of 20-80 ng/ml.
