Application Abreviews Notes
WB Use at an assay dependent concentration. Detects a band of approximately 14 kDa (predicted molecular weight: 10 kDa). To detect hI-TAC by Western Blot analysis this antibody can be used at a concentration of 0.1 - 0.2 µg/ml. Used in conjunction with compatible secondary reagents the detection limit for recombinant hI-TAC is 1.5 - 3.0 ng/lane, under either reducing or non-reducing conditions.
ELISA Use at an assay dependent concentration. To detect hI-TAC by direct ELISA (using 100µl/well antibody solution) a concentration of at least 0.5µg/ml of this antibody is required. This antigen affinity purified antibody, in conjunction with compatible secondary reagents, allows the detection of 0.2 - 0.4 ng/well of recombinant hI-TAC.
Neutralising Use at an assay dependent concentration. To yield one-half maximal inhibition [ND50] of the biological activity of hI-TAC (100 ng/ml), a concentration of 3 µg/ml of this antibody is required.
IHC-P Use at an assay dependent concentration.
ICC/IF Use a concentration of 5 µg/ml.


  • Function

    Chemotactic for interleukin-activated T-cells but not unstimulated T-cells, neutrophils or monocytes. Induces calcium release in activated T-cells. Binds to CXCR3. May play an important role in CNS diseases which involve T-cell recruitment. May play a role in skin immune responses.
  • Tissue specificity

    High levels in peripheral blood leukocytes, pancreas and liver astrocytes. Moderate levels in thymus, spleen and lung. Low levels in placenta, prostate and small intestine. Also found in epidermal basal layer keratinocytes in skin disorders.
  • Sequence similarities

    Belongs to the intercrine alpha (chemokine CxC) family.

  • ab9955 staining CXCL11 in human renal tumor with parenchyma tissue section by Immunohistochemistry (Formalin/PFA fixed paraffin-embedded sections).  The primary antibody was used at 0.125 ug/ml and incubated with sample at 4°C overnight. A HRP-labeled polymer detection system was used with a DAB chromogen. Optimal results for these conditions were acheived without antigen retrieval step.

  • Anti-CXCL11 antibody (ab9955) at 1 µg/ml + Human liver tissue lysate - total protein (ab29889) at 10 µg

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 10 kDa
    Observed band size: 14 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 31 kDa, 45 kDa, 49 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 30 seconds
  • ab9955 staining CXCL11 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 blocking solution for 5 minutes at 25°C. The primary antibody was diluted 1/500 and incubated with the sample for 30 minutes. A biotin-conjugated goat anti-rabbit IgG was used as the secondary antibody, diluted 1/500.

  • ICC/IF image of ab9955 stained A431 cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody ab9955 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
