CEACAM-5 SDS-PAGE

Biotinylated Human CEACAM-5, Fc,Avitag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 90%.

Bioactivity-ELISA
 CEACAM-5 ELISA

Immobilized Biotinylated Human CEACAM-5, Fc,Avitag (Cat. No. CE5-H82F6) at 1 μg/mL (100 μL/well) on streptavidin (Cat. No. STN-N5116) precoated (0.5 μg/well) plate can bind Anti-CEACAM-5 (labetuzumab) Antibody, Human IgG1 with a linear range of 0.5-16 ng/mL (QC tested).

  • Background
    Carcinoembryonic antigen-related cell adhesion molecule 5 (CEACAM5) is also Carcinoembryonic antigen (CEA), Meconium antigen 100, CD antigen CD66e, CEACAM5 belongs to the immunoglobulin superfamily and CEA family. CEACAM5 contains seven Ig-like (immunoglobulin-like) domains. CEACAM5 is homodimer protein which binding of E. coli Dr adhesins leads to dissociation of the homodimer. CEACAM5 is cell surface glycoprotein that plays a role in cell adhesion and in intracellular signaling. CEACAM5 is receptor for E. coli Dr adhesins.
