Human SDF-1beta Recombinant Protein (Animal Free) Lyophilized

Human SDF-1beta Recombinant Protein (Animal Free) Lyophilized from Innovative Research has been recombinantly produced in E. coli. This is a Lyophilized protein buffered in with a purity of ? 98% by SDS-PAGE gel and HPLC analyses..

More Details:

• Species: Human
• Target: CXCL12
• Purity: ? 98% by SDS-PAGE gel and HPLC analyses.
• Source: E. coli
• Storage Conditions: The recombinant protein is stable for at least 2 years from date of receipt at -20°C. Reconstituted protein is stable for at least 3 months when stored in working aliquots with a carrier protein at -20°C. As with any protein, exposing the recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.

Additional Information:
SDF-1? and ? are stromal-derived, CXC chemokines that signal through the CXCR4 receptor. SDF-1? and ? 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? and ? contain the four highly conserved cysteine residues present in CXC chemokines. The mature SDF-1? protein, produced by an N-terminal truncation of two additional amino acids, after removal of the signal sequence, contains 72 amino acid residues. Recombinant Human SDF-1? is an 8.5 kDa protein containing 72 amino acid residues.
