Technical Data
CDX2 (Caudal Type Homeobox 2, Caudal-type Homeobox Protein 2, Homeobox Protein CDX-2, CDX3, CDX-3)
CDX2 is an intestine-specific transcription factor expressed early in intestinal development and may function in the regulation of proliferation and differentia- tion of intestinal epithelial cells. CDX2 is found predominantly on the surface of villi and crypts. Differential expression has been reported in some intestinal cancers. This antibody will help detect CDX2 in normal and uncharacterized tissues.

Suitable for use in Immunohistochemistry. Other applications not tested.

Recommended Dilution:
Immunohistochemistry: 1:50-1:100 for1 hr. at RT
