• Endotoxin Level: < 0.001 EU/μg of the protein by the LAL method

Pharmaceutical Information

• Pharmacodynamics: Binds to the carcinoembryonic antigen, which is a cell surface protein generally overexpressed in colon (and other) cancers. The radioactive Tc99, which is covalently attached to the antibody, allows radiodiagnostic detection of CEA expressing cells and tumors
• Targets: Carcinoembryonic antigen-related cell adhesion molecule 1
