Chemokine (C-X-C motif) ligand 5 (CXCL5) may be involved in neutrophil trafficking in TH17 cell–mediated autoimmunity. It has a role in neutrophil homeostasis at mucosal sites. Murine models of colitis show an increased expression of CXCL5.

General description

The murine homolog of ENA-78 is called LIX or chemokine (C-X-C motif) ligand 5 (CXCL5). 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 9.8kDa protein containing 93 amino acid residues.

Physical form

Lyophilized from 5 mM HoAc.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
