CD66a, known as CEACAM1a, carcinoembryonic antigen-related cell adhesion molecule 1a, is a glycoprotein of the immunoglobulin superfamily and the carcinoembryonic antigen family. Isoforms expressing either two or four alternatively spliced Ig-like domains in mice have been found in a number of epithelial, endothelial, or hematopoietic tissues. CEACAM1a functions as an intercellular adhesion molecule, an angiogenic factor, and a tumor cell growth inhibitor. It also serves as a signal regulatory protein influencing B cell receptor complex-mediated activation. The mouse and human CEACAM1a proteins are targets of viral or bacterial pathogens, respectively. It was reported that targeted disruption of the CEACAM1a gene resulting in a partial ablation of the protein in mice led to reduced susceptibility to virus infection. The antibody recognizes the N-terminal domain of murine CEACAM1a, it does not recognize murine CEACAM1b, an allele in SJL mice.

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.125 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

* Alexa Fluor® 488 has a maximum emission of 519 nm when it is excited at 488 nm.

Application Notes

Mab-CC1 clone recognizes the MHV binding domain of CD66a2. Pretreatment of murine fibroblasts with Mab-CC1 prevented binding of MHV-A59 and protected cells from infection with MHV-A592. SJL/J mice are resistant to MHV as they express an alternative allele, clone Mab-CC1 does not react against SJL/J cells2.

Antigen Details

A glycoprotein of the immunoglobulin (Ig) superfamily and the carcinoembryonic antigen family

CEACAM1a is abundantly expressed on B cells, granulocytes, some NK cells, monocytes, DCs, and NK cells. It is found on epithelial and endothelial cells.

CEACAM1a is involved in cell adhesion, tumor growth, and viral infection. It regulates on BCR activation of B lymphocytes.
