CXCL4 Recombinant Protein

CXCL4 is a CXC chemokine that is expressed in megakaryocytes and stored in the alpha-granules of platelets. CXCL4 is chemotactic towards neutrophils and monocytes and has been shown to inhibit angiogenesis. Recombinant human CXCL4 is a 7.8 kDa protein containing 70 amino acid residues, including the four highly conserved residues present in CXC chemokines.

The lyophilized CXCL4 recombinant protein is stable for at least 2 years from date of receipt at -20˚ C. Reconstituted CXCL4 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚ C. As with any protein, exposing CXCL4 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.
