Applications

Recommended Concentration

Sample

Western Blot

1 µg/mL

Recombinant Cotton Rat CXCL10/IP-10/CRG-2 (Catalog # 1117-IP) under non-reducing conditions only

Neutralization

Measured by its ability to neutralize CXCL10/IP‑10/CRG‑2-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CXCR3. The Neutralization Dose (ND₅₀) is typically 20-40 µg/mL in the presence of 10 µg/mL Recombinant Cotton Rat CXCL10/IP‑10/CRG‑2.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Chemotaxis Induced by CXCL10/IP‑10/CRG‑2 and Neutralization by Cotton Rat CXCL10/IP‑10/CRG‑2 Antibody. Recombinant Cotton Rat CXCL10/IP-10/CRG-2 (Catalog # 1117-IP) chemo-attracts the BaF3 mouse pro-B cell line transfected with mouse CXCR3 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Cotton Rat CXCL10/IP-10/CRG-2 (10 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Cotton Rat CXCL10/ IP-10/CRG-2 Monoclonal Antibody (Catalog # MAB1117). The ND₅₀ is typically 20-40 µg/mL.

Background: CXCL10/IP-10/CRG-2

IP-10, also named mob-1 in rat and crg-2 in mouse, is a member of the non-ELR-motif containing CXC chemokine subfamily and has been designated CXCL10. It is induced in various cell types (including keratinocytes, endothelial cells, fibroblasts, smooth muscle cells, monocytes/macrophages, astrocytes, neutrophils, hepatocytes, T cells, epithelial cells and mesothelial cells) in response to stimulation by type I and/or type II interferon as well as by LPS. IP-10 has been shown to chemoattract activated CD4⁺ and CD8⁺ T cells, activated NK cells and smooth muscle cells. It also induces the adhesion of activated T cells to VCAM and ICAM. In addition, IP-10 has been reported to antagonize the angiogenic activity of FGF. IP-10 binds to and activates CXCR3, the chemokine receptor that is shared by MIG/CXCL9 and I-TAC/CXCL11, two additional non-ELR CXC chemokines that are induced by interferon. Cotton rat IP-10 cDNA encodes a 94 amino acid (aa) residue precursor protein with a putative 21 aa signal peptide and a 73 aa mature protein with one potential N-linked glycosylation site. Mature cotton rat IP-10 shares 66%, 64%, and 66% aa sequence identity with rat, mouse and human IP10, respectively (1‑7).
