Description
CXCL11 also known as I-TAC is belonging to the CXC chemokine family. CXCL11, together with MIG and IP-10, constitute a subset of chemokines that are ligands for CXCR3, a chemokine receptor that is primarily expressed on activated Th1 cells and NK cells. Mouse CXCL11 also shares 36% and 29% aa sequence identity with mouse IP-10 (Crg-2) and mouse MIG, respectively. CXCL11 binds CXCR3 with a higher affinity than CXCL10, suggesting that CXCL11 has the potential to restrain inflammatory autoimmunity. Similar to CXCL10, CXCL11 has been shown to be a chemoattractant for IL-2-activated T-lymphocytes, but not for isolated T-cells, neutrophils or monocytes.CXCL11 is not only a major effector for T cell chemotaxis in the pathophysiology of neuroinflammatory disorders, but also plays a crucial role in migration of activating T cells during IFN-dominated immune responses.

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. |
Shipping and Storage
