Buffer: 0.22 μm filtered protein solution is in PBS.

Handling Advice: Avoid repeated freeze/thaw cycles.

Storage: -20 °C

Storage Comment: Unopened vial can be stored between 2°C and 8°C for one month, at -20°C for six months, or at -70°C for one year.

Target Details

Target: CXCL11 (Chemokine (C-X-C Motif) Ligand 11 (CXCL11))

Alternative Name: CXCL11

Background: CXCL11 is a CXC chemokine lacking the ELR (Glutamate-Leucine-Arginine) tripeptide motif, which is functionally and structurally related to CXCL9 and CXCL10. CXCL11, together with CXCL9 and CXCL10, specifically binds to the G protein-coupled receptor CXCR3 and is involved in chemotaxis of immune cells and angiogenesis. Expression of both CXCR3 and CXCL11 by the Th1-associated cytokine IFNγ creates an amplification loop of cell-mediated immune response between Th1 cells. CXCR7 has been identified as an alternate receptor for CXCL11 and is involved in growth, survival, and adhesion of tumor cells.

Molecular Weight: The 80 amino acid recombinant protein has a predicted molecular mass of approximately 9.1 kDa. The DTT-reduced protein migrates at approximately 11 kDa and non-reduced protein migrates at approximately 13 kDa by SDS-PAGE. The N-terminal amino acid is Meth
