特徴

• 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. Recombinant human SDF-1alpha is an 8kD protein containing 68aa.
• Source:Recombinant protein corresponding to human SDF-1 alpha, expressed in E.coli.
• Biological Activity:Determined by its ability to chemoattract human peripheral T cells activated with PHA and IL-2 using a concentation of 20-80ng/ml.
• Endotoxin:<0.1ng/ug (1EU/ug)
