Background: SDF-1alpha and SDF-1beta are small cytokines belonging to the CXC- Chemokines. SDF-1 is identical with a chemokine reported to function as a pre-B-cell growth factor in the presence of IL-7 and isolated originally from a murine bone marrow stromal cell line. Human SDF-1alpha and SDF-1beta are encoded by a single gene and arise by alternative splicing. SDF-1 acts on lymphocytes and monocytes but not neutrophils in vitro and is a highly potent chemoattractant for mononuclear cells in vivo. In addition, SDF-1 also induces intracellular actin polymerization in lymphocytes. SDF acts as a chemoattractant for human hematopoietic progenitor cells expressing CD34 giving rise to mixed types of progenitors, and more primitive types. The chemotactic response is inhibited by pertussis toxin. Chemotaxis of CD34(+) cells in response to SDF is increased by IL-3 in vitro. SDF has been shown also to induce a transient elevation of cytoplasmic calcium in these cells.

Description: Recombinant murine stromal cell-derived factor-1beta (SDF1β), also known as CXCL12 or Pre-B cell growth-stimulating factor (PBSF), is a disulfide-linked monomeric protein consisting of 73 a.a. and migrates as an approximately 8 kDa protein under reducing and non-reducing conditions. Optimized DNA sequence encoding mouse Stromal Cell-Derived Factor-1 beta (SDF1β) mature chain was expressed in E. coli.
