Weitere Details:: 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 rat SDF-1 alpha is a 7.9kD protein containing 68aa. Source: Recombinant protein corresponding to rat SDF-1 alpha, expressed in E.coli. Biological Activity: Determined by its ability to chemoattract human peripheral blood monocytes using a concentration range of 50-100ng/ml. Endotoxin: <0.1ng/ug (1EU/ug) AA Sequence: KPVSLSYRCP CRFFESHVAR ANVKHLKILN TPNCALQIVA RLKSNNRQVC IDPKLKWIQE YLDKALNK Storage and Stability: May be stored at 4°C for short-term only.
