Recombinant Mouse SDF-1 Beta/CXCL12 Beta protein

SKU: CD00238

Size:2 ug

Background:CXCL12 also known as SDF-1 is belonging to the CXC chemokine family. Mouse CXCL12 is expressed as two isoforms that differ only in the C-terminal tail. Both SDF-1 isoforms undergo proteolytic processing of the first two N-terminal amino acids. In all SDF-1 isoforms, SDF-1β is the canonical sequence. It has the complete amino acids in the C-terminal tail. On the cell surface, the receptor for this chemokine is CXCR4 and syndecan4. CXCL12 is strongly chemotactic for T-lymphocytes, monocytes, but not neutrophils. SDF-1 is highly conserved between species, Mouse CXCL12β shares approximately 92 % amino acid sequence identity with human CXCL12β.
