Synonymes: Pbsf Protein, Scyb12 Protein, Sdf1 Protein, Tlsf Protein, Tpar1 Protein, sdf1a Protein, SDF-1 Protein, chemokine (C-X-C motif) ligand 12 Protein, C-X-C motif chemokine ligand 12 Protein, Cxcl12 Protein, cxcl12 Protein, CXCL12 Protein

Sujet: SDF-1ª and beta are stromal derived CXC chemokines, and signal through the CXCR4 receptor. SDF-1ª 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. Synonym: SDF-1beta/CXCL12, Rat. Formulation: Lyophilized from a 0.2µm filtered concentrated solution in 20mM PB, pH 7.4, 150mM NaCl.

Poids moléculaire: 7.9 kDa, a single non-glycosylated polypeptide chain containing 72 amino acids.
