Overview

Carcinoembryonic antigen is a protein encoded by the CEACAM5 gene which is approximately 76, 7 kDa. Carcinoembryonic antigen is localised to the cell membrane. It is involved in the metabolism of proteins and hematopoietic stem cell differentiation pathways and lineage-specific markers. It is a cell surface glycoprotein that plays a role in cell adhesion and in intracellular signalling. It may also regulate differentiation, apoptosis, and cell polarity and is used as a clinical biomarker for gastrointestinal cancers. Carcinoembryonic antigen is expressed in the intestine, liver, saliva, stomach and lung. Mutations in the CEACAM5 gene may be involved in urachal cancer. STJ96963 was developed from clone 10E1 and was affinity-purified from mouse ascites by affinity-chromatography using specific immunogen. This primary antibody detects endogenous Carcinoembryonic antigen proteins.
