Product Overview
Clone 19C82 is a rabbit monoclonal antibody that recognizes homeobox protein CDX-1 (gene CDX1) in human samples and is validated for Western blot and ICC/IF. The predicted molecular weight is 28.1 kDa, and the supplier reports an observed band at about 28 kDa.
CDX-1 is a caudal-type homeobox transcription factor expressed in the intestinal epithelium. It regulates genes involved in intestinal cell differentiation and in anterior-posterior patterning during development, and it is studied in intestinal biology and colorectal cancer.

Immunogen
Synthetic peptide based on the sequence of human cdx1.
Reactivity Notes
The supplier lists reactivity with human. UniProt places homeobox protein CDX-1 in the nucleus. Tissue expression noted by UniProt (human): Intestinal epithelium. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

Customization & Add-ons: Can’t find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
