Recommended Concentration

Reagent

ELISA Capture (Matched Antibody Pair)

2-8 µg/mL

Use in combination with:

Detection Reagent: Human CXCL10/IP‑10/CRG‑2 Biotinylated Antibody (Catalog # BAF266)

Standard: Recombinant Human CXCL10/IP-10 Protein (Catalog # 266-IP)

Neutralization

Measured by its ability to neutralize CXCL10/IP‑10/CRG‑2-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR3. The Neutralization Dose (ND₅₀) is typically 0.5-2.0 µg/mL in the presence of 0.2 µg/mL Recombinant Human 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.

Detection of CXCL10 in Human PBMCs by Flow Cytometry. Human PBMCs were treated with recombinant human INF gamma (Catalog # 285-IF, 10 ng/ml) overnight and stained with Mouse Anti-Human CXCL10 Monoclonal Antibody (Catalog # MAB266R, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram) followed by anti-Mouse IgG PE-conjugated secondary antibody (Catalog # F0102B). To facilitate intracellular staining, cells were fixed with Flow Cytometry Fixation Buffer (Catalog # FC004) and permeabilized with Flow Cytometry Permeabilization/Wash Buffer I (Catalog # FC005).

Neutralization

Chemotaxis Induced by CXCL10/IP-10 and Neutralization by Human CXCL10/IP-10 Antibody. Recombinant Human CXCL10/IP-10 (Catalog # 266-IP) chemoattracts the BaF3 mouse pro-B cell line transfected with human 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 Human CXCL10/IP-10 (0.2 µg/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human CXCL10/IP-10 Monoclonal Antibody (Catalog # MAB266). The ND₅₀ is typically 0.5-2.0 µg/mL.

Background: CXCL10/IP-10/CRG-2

CXCL10 was originally identified as an IFN-gamma -inducible gene in monocytes, fibroblasts and endothelial cells. It has since been shown that CXCL10 mRNA is also induced by LPS, IL-1 beta, TNF-alpha, IL-12, and viruses. Additional cell types that have been shown to express CXCL10 include activated T-lymphocytes, splenocytes, keratinocytes, osteoblasts, astrocytes, and smooth muscle cells. CXCL10 is also expressed in psoriatic and lepromatous lesions of skin. The mouse homologue of human CXCL10, CRG-2, has been cloned and shown to share approximately 67% amino acid sequence identity with human CXCL10. Human CXCL10 cDNA encodes a 98 amino acid (aa) residue precursor protein with a 21 aa residue signal peptide that is cleaved to form the 77 aa residue secreted protein. The amino acid sequence of CXCL10 identified the protein as a member of the chemokine alpha subfamily that lacks the ELR domain. CXCL10 has been shown to be a chemoattractant for activated T-lymphocytes. CXCL10 has been reported to be a potent inhibitor of angiogenesis and to display a potent thymus-dependent antitumor effect. A chemokine receptor specific for CXCL10 and Mig has been cloned and shown to be highly expressed in IL-2-activated T-lymphocytes.
