Description
Alternate Names: CXCL12, PBSF Accession Number: P48061
Description: Stromal cell-derived factor-1 alpha (SDF-1 α), also called CXCL12a, is one of two SDF-1 splice variants made by a wide variety of cells upon stimulation by inflammatory cytokines such as TNF, IL-1, and LPS. SDF-1α signals through the G protein-coupled receptor CXCR4 to recruit activated leukocytes. Human and mouse SDF-1 α share 99% sequence identity.
Source: Genetically modified E.coli.
Predicted MW: Monomer, 8 kDa (68 aa) ***Under non-reducing conditions, samples prepared at higher working concentrations are shown to produce a band of approximately 16 kDa on an SDS PAGE gel, which may represent dimer formation.
