名称：精品原装| Recombinant Human SDF-1beta (CXCL12)
Purity: Greater than 98% by SDS-PAGE gel and HPLC analyses.
Source: E.coli. 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. SDF-1α and β are stromal derived CXC chemokines, and signal through the CXCR4 receptor.
Additionally, the SDF-1 proteins exert HIV suppressive activity in cells expressing the CXCR4 receptor. SDF-1α and β chemoattract B and T cells, and have been shown to induce migration of CD34+ stem cells. Recombinant human SDF-1β is an 8.5 kDa protein containing 72 amino acid residues. Synonyms: Stromal-Cell Derived Factor-1,CXCL12,PBSF.
