Product Summary for CXCR3 Antibody


This antibody was developed against a synthetic peptide corresponding to amino acids 290-303 of human CXCR3.







Theoretical MW

41 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Scientific Data Images for CXCR3 Antibody

Western Blot: CXCR3 Antibody [NB100-56404] - HEK293T cells. Western blot image submitted by a verified customer review.
Immunocytochemistry/Immunofluorescence: CXCR3 Antibody [NB100-56404] - Brain microvascular endothelial cells isolated from WT and CXCR3 KO mice were stained with anti-CXCR3 (green) and anti-ZO-1 (blue) antibodies to analyze CXCR3 expression by immunofluorescence. Image from verified customer review.
Immunohistochemistry-Paraffin: CXCR3 Antibody [NB100-56404] - IHC analysis of a FFPE human spleen using 1:25 dilution of CXCR3 antibody on a Bond Rx autostainer (Leica Biosystems). The assay involved 20 minutes of HIER using 10mM sodium citrate buffer (pH 6.0) and endogenous peroxidase quenching with peroxide block. The sections were incubated with primary antibody for 30 minutes and Bond Polymer Refine Detection (Leica Biosystems) with DAB was used for signal development followed by counterstaining with hematoxylin. Whole slide scanning and capturing of representative images (40X) was performed using Aperio AT2 (Leica Biosystems). Staining was performed by Histowiz.

Background: CXCR3

Chemokines play important roles in inflammation and critical for the recruitment of effector immune cells to sites of infection. Historically, CD183 was the third CXC chemokine receptor discovered and therefore, commonly designated as CXCR3. Binding of chemokines to CD183 induces cellular responses that are involved in leukocyte traffic, most notably integrin activation, cytoskeletal changes and chemotactic migration. The CXC chemokine receptor (CXCR) 3, a G-protein-coupled 7-transmembrane receptor, is expressed at high levels on activated and memory T cells, B cells, natural killer cells, and plasmacytoid monocytes.

FAQs for CXCR3 Antibody

Showing  1 - 2 of 2 FAQs Showing All
  • Q: Regarding recommended dilutions the manual contains: "Immunohistochemistry-Paraffin, Western Blot 1-3 ug/ml" Does it mean 1-3 ug/ml is recommended for both applications or there is simply no recommended dilution IHC-P?

    A: For our product NB100-56404, we did not have a dilution recommendation listed for IHC on our datasheet. I am sorry for any confusion. This application was added to our product based on a publication that actually uses this product at 1:200 in paraformaldehyde fixed frozen tissue samples: NCBI site.

  • Q: Which isoform of CXCR3 is this antibody specific for?

    A: NB100-56404 can only detect human CXCR3 isoforms 1 and 2 in WB and IHC-Fr, the validated applications.
