SDF1 – Stromal Cell-Derived Factor 1α ( CXCL12) tested in migration, LPS-Free
Recombinant Stromal Cell-Derived Factor 1α (SDF-1α) is a 8 kDa chemokine protein expressed in many tissues and cell types.
The protein is almost identical (92% homology) in human, mouse and rat.
The chemokine SDF-1α binds to the chemokine receptor CXCR4 and plays an essential and unique role in homeostatic regulation of leukocyte traffic, hematopoiesis, organogenesis, cell differentiation and tissue regeneration (Murphy, 2002).
SDF-1α forms an heterocomplex with the alarmin HMGB1 (High Mobility Group 1) to promote the recruitment of cells via CXCR4 receptor.
It has the sequence:
["MKPVSLSYRCPCRFFESHVARANVKHLKILNTPNCALQIVARLKNNNRQVCIDPKLKWIQEYLEKALNK"]
Molecular Mass: Stromal Cell-Derived Factor 1α (SDF-1α, CXCL12) consists of 69 amino acid residues and has a calculated molecular mass of approximately 8 kDA
Purity: The purified protein is >95% homogeneous (electrophoresis). It contains no nucleic acids.
Endotoxin Level: The purified protein is free from LPS (Pierce™ Chromogenic Endotoxin Quant Kit, <0.1 EU/mL). The product contains <0.006% v/v of Triton X-114 due to LPS removal procedure. The remaining traces of Triton X-114 can be removed upon request.
Activity: Measured by its ability to induce migration. Maximal activity in the cell migration assay is obtained at 1 nM.
Buffer & Reconstitution: the lyophilized protein once reconstituted with distilled water will be dissolved in a solution of DPBS without Ca and Mg.
Storage: 2-8°C when lyophilized. The protein once reconstituted with water can be stored frozen (-20°C). Avoid repeated freezing and thawing.Please contact us at for specific academic pricing.
