LIX is a CXC chemokine that signals through the CXCR2 receptor. It is expressed in monocytes, platelets, endothelial cells, and mast cells. LIX is a chemoattractant for neutrophils. The two naturally occurring variants of LIX; LIX 1-78 (GCP-2) and LIX 9-78 (GCP-2), contain 78 and 70 amino acid residues, respectively. LIX contains the four conserved cysteine residues present in CXC chemokines, and also contains the `ELR' motif common to CXC chemokine that bind to the CXCR1 and CXCR2 receptors. Recombinant murine LIX is a 9.8 kDa protein containing 92 amino acid residues. MW: 9.8 kDa. Purity ≥ 98%
