Purified recombinant Human SDF1 alpha protein Expression System: E.coli Bioactivity: Determined by its ability to chemoattract human peripheral blood monocytes using a concentration range of 50.0-100.0 ng/mL.
SDF-1 alpha 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. Alternative Names: SDF-1 alpha protein, CXCL12 protein, Stromal-Cell Derived Factor-1 protein, SDF-1 alpha protein, SDF1 alpha, PBSF protein, SDF-1 alpha, SDF 1 alpha protein, SDF 1 alpha
