Description

CXCL16 is a member of the CXC chemokine family. Mouse CXCL16 has 246 a.a. and consists of a 26 a.a. residue putative signal peptide, an 88 a.a. residue chemokine domain, an 87 a.a. residue mucin-like spacer region, a 22 a.a. residue transmembrane domain, and a 23 a.a. residue cytoplasmic tail. Mouse and human CXCL16 share 49% overall aa identity and 70% similarity in the chemokine domains. CXCL16 is a transmembrane chemokine and is implicated in activated CD8+ T cell trafficking. CXCL16 mediates adhesion and phagocytosis of both Gram-negative and Gram-positive bacteria and is a strong chemoattractant for CXCR6+ T cells. It facilitates uptake of low density lipoproteins by macrophages, resulting in foam cell formation.

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

>98% by SDS-PAGE and HPLC analyses.

Biological Activity

The biological activity determined by a chemotaxis bioassay using mouse lymphocytes is in a concentration of 20-1000 ng/mL. Fully biologically active when compared to standard.

Endotoxin

< 1.0 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS.

Reconstitution

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20℃. Further dilutions should be made in appropriate buffered solutions.
