Endotoxin Level: Predicted Molecular Mass:11.6 kDa SDS-PAGE:14 kDa, reducing conditions Activity:Measured by its ability to chemoattract BaF3 mouse pro‑B cells transfected with human CXCR4.

    The ED50 for this effect is typically 4 - 24 ng/mL.

    Molecule Information: CXCL12/SDF-1 gamma Long Name: CXCL12/Stromal cell-Derived Factor 1 Entrez Gene IDs: 6387 (Human) Background: CXCL12/SDF-1 (PBSF) Stromal cell-derived factor (SDF)-1 alpha and SDF-1 beta are the first cytokines initially identified using the signal sequence trap cloning strategy from a mouse bone-marrow stromal cell line. They are encoded by a single gene, PBSF, and arise by alternative splicing. The two proteins are identical except for the four amino acid residues that are present in the carboxy-terminus of SDF-1 beta and absent from SDF-1 alpha. SDF-1/PBSF is highly conserved between species. Human mature SDF-1 shares approximately 99% amino acid sequence identity with the mouse protein.
