Description

Chemokine CXCL9 is a member of the CXC family and has an important role in the chemotaxis of immune cells. The mouse CXCL9 shares 75% and 88% a.a. sequence identity with human and rat CXCL9. Accumulated experimental evidence supports that monokine induced by interferon (IFN)-gamma (CXCL9), a member of CXC chemokine family and known to attract CXCR3- (A and B) T lymphocytes, is involved in the pathogenesis of physiologic diseases during their initiation and their maintenance. It is a cytokine that affects the growth, movement, or activation state of cells that participate in immune and inflammatory response and chemotactic for activated T-cells.

Appearance

Sterile Filtered White lyophilized (freeze-dried) powder.

Purity

>96% by SDS-PAGE and HPLC analyses.

Biological Activity

The biological activity determined by a chemotaxis bioassay using human lymphocytes is in a concentration range of 0.1-1.0 ng/mL. 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 20 mM PB, pH 7.0, 500 mM NaCl.

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.
