CDX2 in SW480 Human Cell Line. CDX2 was detected in immersion fixed SW480 human colorectal adenocarcinoma cell line using Mouse Anti-Human CDX2 Monoclonal Antibody (Catalog # MAB3665) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

CDX2 in Human Colon Cancer Tissue. CDX2 was detected in immersion fixed paraffin-embedded sections of human colon cancer tissue using Mouse Anti-Human CDX2 Monoclonal Antibody (Catalog # MAB3665) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to nuclei.

Background: CDX2

Human CDX2 (Caudal type homeobox transcription factor 2) is a 37 kDa member of the caudal family of homeobox proteins. It is 313 amino acids (aa) in length and contains a 167 aa caudal-like activation domain (aa 13‑180), a DNA-binding homeodomain (aa 186‑245) and two short, poly-glutamine and -proline repeats. CDX2 can exist as a dimer and is regulated by phosphorylation of a 4(x)serine motif that promotes CDX2 degradation. CDX2 promotes intestinal patterning and development. While it is necessary but not sufficient for intestinal phenotype differentiation, it will block cell proliferation on its own. Over the amino acid range used for immunization, human CDX2 is 95% and 97% aa identical to mouse and canine CDX2, respectively.
