Chemokine (CXC motif) ligand 16, is a small cytokine belonging to the CXC chemokine family and signals through the CXCR6 receptor. CXCL16 is composed of its typical CXC chemokine domain, a mucin-like stalk, a transmembrane domain, and a cytoplasmic tail which allow CXCL16 to act as a cell surface bound molecule as well as a soluble chemokine. Human CXCL16 shares 70% amino acid sequence similarity with the mouse and CXCL16 expression is induced by IFN-γ and TNF-α. CXCL16 is produced by dendritic cells in lymphoid organs, and by red pulp spleen cells. The expression of CXCL16 may attract lymphocytes during inflammation and assist some immune responses.
Aliases- Scavenger receptor for phosphatidylserine and oxidized low density lipoprotein, µmall-inducible cytokine B16, transmembrane chemokine CXCL16
Formulation- Lyophilized from a 0.2 µm filtered solution in PBS
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity.
Avoid repeated freeze/thaw cycles.
