PE-Labeled CEACAM-5/CD66e Fc&Avi Tag is an advanced recombinant protein probe specifically designed for a key member of the carcinoembryonic antigen family. Carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM-5), a member of the immunoglobulin superfamily, is minimally expressed in normal adult tissues such as colonic mucosa but exhibits specific overexpression in various epithelial-derived malignancies, including colorectal cancer, non-small cell lung cancer, gastric cancer, breast cancer, and pancreatic cancer. It serves as one of the most widely used serum tumor markers and a highly promising therapeutic target.
