SDF-1 alpha (CXCL12) Antibody

SDF-1 alpha andbeta are stromal-derived, CXC chemokines that signal through the CXCR4 receptor. SDF-1alpha andbeta chemoattract B and T cells, and have been shown to induce migration of CD34+ stem cells. Additionally, the SDF-1 proteins exert HIV-suppressive activity in cells expressing the CXCR4 receptor. Human and murine SDF-1 proteins act across species. SDF-1 alpha andbeta contain the four highly conserved cysteine residues present in CXC chemokines. The mature SDF-1 alpha protein is the result of alternative splicing of the SDF-1 gene and contains 68 amino acid residues. Recombinant Rat SDF-1alpha is a 7.9 kDa protein containing 68 amino acid residues.

Produced from sera of rabbits immunized with highly pure recombinant Rat SDF-1 alpha. Anti-Rat SDF-1 alpha-specific antibody was purified by affinity chromatography employing an immobilized Rat SDF-1 alpha matrix.

Antibody is stable for at least 2 years from date of receipt at -20˚ C. The reconstituted antibody is stable for at least two weeks at 2-8˚ C. Frozen aliquots are stable for at least 6 months when stored at -20˚ C. Avoid repeated freeze-thaw cycles.
