This antibody is intended for in vitro diagnostic (IVD) use.
The CDX-2 (IHC402) antibody is intended for qualified laboratories to qualitatively identify by light microscopy the presence of associated antigens in sections of formalin-fixed, paraffin-embedded tissue sections using IHC test methods. Use of this antibody is indicated, subsequent to clinical differential diagnoses of diseases, as an aid in the identification of gastrointestinal malignancies within the context of antibody panels, the patient’s clinical history and other diagnostic tests evaluated by a qualified pathologist.
CDX-2 is a caudal-related homeobox transcription factor that is expressed by intestinal epithelial cells. CDX-2 is a useful marker for gastrointestinal carcinoma, and for determining the origin of gastrointestinal metastatic adenocarcinoma and carcinoids. Anti-CDX-2 is used for differentiating lung and metastatic colorectal adenocarcinoma, however mucinous ovarian carcinoma also react positively with Anti-CDX-2, thereby limiting the ability to differentiate from metastatic colorectal adenocarcinoma.
