Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM-1) is the major antigen of the CD66 cluster of granulocyte differentiation antigens. The present study aimed to assess the biological function of CEACAM-1 on the growth of human colorectal cancer (CRC) cells in vitro. CEACAM1 Protein, Canine, Recombinant (His) is expressed in HEK293 mammalian cells with C-His tag. The predicted molecular weight is 43.62 kDa and the accession number is XP_038509497.1.
