Description

CXCL17 also named dendritic cell and monocyte chemokine-like protein (DMC) and VEGF co-regulated chemokine 1 (VCC-1), is a small cytokine belonging to the CXC chemokine family. CXCL17 was the last chemokine ligand to be described and is the 17th member of the CXC chemokine family. Its strategic expression in mucosal tissues suggests that it is involved in innate immunity and/or sterility of the mucosa. Mature human DMC shares 73%, 71% and 64% amino acid sequence identity with bovine, mouse and rat DMC, respectively. It may be a housekeeping chemokine regulating recruitment of nonactivated blood monocytes and immature dendritic cells into tissues and may play a role in the innate defense against infections. CXCL17 also has a role in angiogenesis of importance for tumour development.

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

>96% by SDS-PAGE and HPLC analyses.

Biological Activity

The ED50 as determined by its ability to induce VEGF expression using murine endothelial cells is less than 5.0 μg/ml, corresponding to a specific activity of > 200 IU/mg. Fully biologically active when compared to standard.

Endotoxin

< 0.1 EU per 1μg of the protein by the LAL method.

Formulation

Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4, with 3 % Trehalose.

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.
