| Description | Carcinoembryonic Antigen-related Cell Adhesion Molecule 1 (CEACAM-1), also known as CD66a and BGP-I, is a 115 kDa type I transmembrane glycoprotein that belongs to the membrane-bound CEA subfamily of the CEA superfamily. On the surface of cells, it forms noncovalent homo- and heterodimers. The extracellular region contains three C2-type Ig-like domains and one N-terminal V-type Ig-like domain. Multiple splice variants involving regions C-terminal to the second C2-type domain (aa 320 and beyond) exist. |

Flow cytometry with stably transfected HeLa cells: 250.000 Hela-human CEACAM1 cells; 10 µg/ml of primary B3-17 [Cat# 101-M182]. Binding was detected with a FITC-conjugated secondary antibody.
The experiments were performed by PD Dr. Bernhard Singer, Institute of Anatomy, Medical Faculty, University Duisburg-Essen, Germany.
IHC staining of human jejunum tissue with mAb B3 [Cat# 101-M182]. CEACAM1 was detected in PFA-fixed paraffin-embedded sections of human jejunum tissue using mAb B3 [Cat# 101-M182] followed by staining with antimouse HRP-DAB and counterstaining with hematoxylin. The labeling showed week staining of CEACAM1 by B3.

Western blot analysis: Human CEACAM1 lysate
Detection utilizing 10 µg/ml [Cat# 101-M182]
The experiments were performed by PD Dr. Bernhard Singer, Institute of Anatomy, Medical Faculty, University Duisburg-Essen, Germany.
Sandwich ELISA: Solid phase was coated with 3 µg/ml anti-CEA (Dako) binding human CEACAM1. After washing, blocking and coating human CEACAM1 antigen, detecting antibody B3-17 [Cat# 101-M182] (10 µg/ml) followed by HRP-coupled goat anti-mouse Ig was added. TMB was used for visualizing the binding measured by Tecan-ELISA reader at 450 nm.
NOTE: In Sandwich ELISA B3-17 [Cat# 101-M182] can also be used as catcher antibody.

Immunofluorescence with HeLa-CEACAM1 cells. Cells were fixed with 4% PFA (10min) and then incubated in 5% BSA/PBS for 1h to block non-specific protein-protein interactions. The cells were then incubated with 10µg B3-17 [Cat# 101-M182] overnight at 4°C. The secondary antibody (green) was Alexa Flour® 488 goat-anti-mouse IgG (H+L).
The experiments were performed by PD Dr. Bernhard Singer, Institute of Anatomy, Medical Faculty, University Duisburg-Essen, Germany.
