      CXCL12 is belonging to the CXC chemokine family. CXCL12 is strongly chemotactic for T-lymphocytes, monocytes, but not neutrophils. Contrast to SDF-1β, SDF-1α is shorter by four amino acids at the C-terminal tail. CXCL12 is strongly chemotactic for T-lymphocytes, monocytes, but not neutrophils. SDF-1 is highly conserved between species, rat CXCL12α shares approximately 96% amino acid sequence identity with human CXCL12α. SDF-1 is highly conserved between species, rat CXCL12α shares approximately 96% amino acid sequence identity with human CXCL12α.

      Reconstitution
      
			      		
			
			
      We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
