Human stromal cell-derived factor-1β (SDF-1β) is a member of the CXCL chemokine family that signals through the CXCR4 receptor. CXCL12 is strongly chemotactic for lymphocytes and induce migration of CD34+ stem cells. In cells expressing the CXCR4 receptor, CXCL12 exerts HIV-suppressive activity.

The mature SDF-1β protein is the product of alternative splicing of the SDF-1 gene and contains 72 amino acid residues. Human and murine SDF-1 proteins act across species. Recombinant human SDF-1β is an 8.5 kDa protein containing 72 amino acid residues.

Biological Activity

Determined by its ability to chemoattract human peripheral T cells activated with PHA and IL-2 using a concentration range of 20-80 ng/ml.
