Our Abpromise guarantee covers the use of ab240936 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use at an assay dependent concentration.

Antigen retrieval is recommended: Boil tissue section in 10mM Citrate buffer, pH 6.0 for 10-20 min followed by cooling at RT for 20 min.


Flow Cyt Use at an assay dependent concentration.

ab199376 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.


  • Function

    Involved in the transcriptional regulation of multiple genes expressed in the intestinal epithelium. Important in broad range of functions from early differentiation to maintenance of the intestinal epithelial lining of both the small and large intestine.
  • Sequence similarities

    Belongs to the Caudal homeobox family.
    Contains 1 homeobox DNA-binding domain.
  • Post-translational

    Phosphorylation of Ser-60 mediates the transactivation capacity.
  • Cellular localization

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human colon carcinoma tissue sections labeling CDX2 with ab101532 at 1/100 dilution (1.11 μg/ml). Heat mediated antigen retrieval with Citrate buffer (pH 6.0, epitope retrieval solution 1) for 20 mins. Goat Anti-Rabbit & Mouse IgG (HRP) was used as the secondary antibody. Hematoxylin was used as a counterstain. Positive staining on the human colon carcinoma, performed on a Leica Biosystems BOND™ RX instrument.
    The section was incubated with ab101532 for 30 mins at room temperature.

    This image was generated using ab101532, the same clone, but with a different buffer formulation.

  • Staining of CDX2 in a Formalin/PFA-fixed paraffin-embedded section of human colon carcinoma tissue using ab101532 at a dilution of 1/100.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, and sodium azide (ab101532)

  • Flow cytometric analysis of rabbit anti-CDX2 (SP54) antibody ab101532(1/100) in HT29 cells (green) compared to negative control of rabbit IgG (blue).

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, and sodium azide (ab101532)
