Recombinant Human SDF-1α (CXCL12)
| Synonyms: | Stromal-Cell Derived Factor-1, CXCL12, PBSF |
| Description: | SDF-1α and beta are stromal derived CXC chemokines, and signal through the CXCR4 receptor. SDF-1alpha and beta 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. Recombinant human SDF-1α is an 8.0 kDa protein containing 68 amino acid residues. |
| Source: | E.coli |
| Stability: | The lyophilized protein is stable for at least 2 years from date of receipt at -20C. Reconstituted SDF-1α is stable for at least 3 months when stored in working aliquots with a carrier protein at -20C. Avoid repeated freeze/thaw cycles. |
| Purity: | Greater than 99% by SDS-PAGE gel and HPLC analyses. |
| Biological Activity: | Determined by its ability to chemoattract human peripheral T cells activated with PHA and IL-2 using a concentation of 20-80 ng/ml. |
