  • Function
    Receptor for CXCL9, CXCL10 and CXCL11 and mediates the proliferation of human mesangial cells (HMC).
    Isoform 2 is a receptor for CXCL4 and also mediates the inhibitory activities of CXCL9, CXCL10 and CXCL11 on the growth of human microvascular endothelial cells (HMVEC). May play a role in angiogenesis.
    Isoform 3 mediates the activity of CXCL11.
  • Tissue specificity
    Isoform 1 and isoform 2 are mainly expressed in heart, kidney, liver and skeletal muscle. Isoform 1 is also expressed in placenta.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Cellular localization
    Cell membrane.

  • ab64714 staining CXCR3 in primary cultured HUVEC by ICC/IF (Immunocytochemistry/immunofluorescence). Cells were fixed with acetone and blocked with 5% serum for 30 minutes at 24°C. Samples were incubated with primary antibody (1/400 in PBS + 2.5% serum) for 16 hours at 4°C. An Alexa Fluor®488-conjugated Goat anti-mouse IgG polyclonal (1/500) was used as the secondary antibody.

  • ab64714 staining CXCR3 in pig uterus tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded tissue sections). The sections were fixed in paraformaldehyde and subjected to enzymatic antigen retrieval prior to blocking with 10% serum for 20 minutes at 24°C. The primary antibody was diluted 1/200 and incubated with the sample for 30 minutes at 24°C. A biotin-conjugated ABC kit was used to detect the antibody.

  • The chemoattractive activity of recombinant human CXCL11 (7 ng/ml) towards B cells transfected with human CXCR3 is neutralized in a dose-dependent manner by ab64714 (green). The IC50 for neutralization is typically 0.3 - 1.5 μg/ml.

  • Flow Cytometry of HEK293 cells transfected with human CXCR3 (upper histogram) or with irrelevant transfectants and eGFP (lower histogram) were stained with ab64714(10μl undiluted antibody per 1 x10cells) followed by APC conjugated anti-mouse IgG secondary antibody.

  • ab64714 staining CXCR3 in Human glioblastoma tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded tissue sections). The sections were fixed in formaldehyde and subjected to heat-mediated antigen retrieval in citrate buffer prior to blocking with a proprietary non-protein reagent for 5 minutes at 25°C. The primary antibody was diluted 1/2000 and incubated with the sample for 30 minutes. A biotin-conjugated goat anti-mouse IgG was used as the secondary antibody.

Thank you for your inquiry.

The immunogen for this antibody was the full length human CXCR3 (aa1-368, according to Accession # P49682).

To our knowledge the exact epitope was not further mapped.

I am sorry that I could not provide you with a more detailed answer and hope this information is nevertheless helpful.

Thank you for contacting us.
Unfortunately we have not tested this antibody in mouse samples so do not have any experimental evidence of the use of it with this species.
The epitope is not mapped, so it is not possible to predict the extent of reactivity of this antibody with mouse tissue samples.
I am sorry I don’t have more information available. In any case, if you are interested in participating in our antibodies evaluation system (Abreview), and test ab64714 with Mouse I will be happy to offer a discount code for a future purchase if you submit the results (in a form of an Abreview) to our website.
It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback. The discount would be to the value of 1 free primary antibody.
If you are interested in this offer, please let me know before placing the order.
