Specifications

PF-4 is a CXC chemokine that is expressed in megakaryocytes and stored in the alpha-granules of platelets.PF-4 is chemotactic towards neutrophils and monocytes and has been shown to inhibit angiogenesis.Recombinant murine PF-4 is an 8.2kD protein containing 76 amino acid residues, including the four highly conserved residues present in CXC chemokines.

Storage and StabilityStore lyophilized products at -20°C. For reconstituted solutions of most products, we recommend short-term storage at 4°C. For longer term storage the protein solution should be stored with a carrier protein (eg. 0.1% BSA) in working aliquots and stored frozen at -20°C. Additional freeze/thaw cycles may cause some denaturation of the protein.
