特徴

• 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 7.8kD protein containing 70aa, including the four highly conserved residues present in CXC chemokines.
• Source:Recombinant protein corresponding to human CXCL4, expressed in E. coli.
• Biological Activity:Determined by its ability to chemoattract human fibroblasts using a concentration range of 1-10ng/ml.
• Endotoxin Level:<0.1ng/ug (1EU/ug)
• AA Sequence:EAEEDGDLQC LCVKTTSQVR PRHITSLEVI KAGPHCPTAQ LIATLKNGRK ICLDLQAPLY KKIIKKLLES
