Recombinant Human CXCL16

• Description:

  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.

• Gene Name:

  Scavenger receptor for phosphatidylserine and oxidized low density lipoprotein, Small-inducible cytokine B16, transmembrane chemokine CXCL16

• Gene ID:

  58191

• Accession Number:

  Q9H2A7

• Organism:

  Human

• Source:

  E. coli

• Concentration:

  <1.0 EU/μg of recombinant protein as determined by the LAL method

• Purity:

  >95% as determined by SDS-PAGE

• Solubility:

  A quick spin of the vial followed by reconstitution in sterile distilled water to a concentration not less than 0.1 mg/mL. This solution can then be diluted into other buffers.

• Function:

  The ED50 is 2.5-12 ng/mL as determined by its ability to chemoattract activated lymphocytes (at a concentration of 100.0 ng/mL)

  10.4

• Shipping Conditions:

  Ambient Temperature

• Storage Conditions:

  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° - 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.
