This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab133633). Western blot : Anti-CEACAM5 antibody [EPCEAR7] (ab133633) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in magenta. In Western blot, ab133633 was shown to bind specifically to CEACAM5. A band was observed at 160-180 kDa in wild-type A549 cell lysates with no signal observed at this size in CEACAM5 knockout cell line. To generate this image, wild-type and CEACAM5 knockout A549 unboiled cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3% milk in TBS-0.1% Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4°C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

Biological function summary
CEACAM5 contributes to cellular processes involving cell adhesion and immune response modulation. This protein operates as part of a larger group of cell adhesion molecules and does not function as part of a complex. CEACAM5 can affect the interactions between cells and the extracellular matrix which has implications for tissue structuring and integrity. It helps the immune system recognize and respond to infectious agents or cellular anomalies.
Pathways
CEACAM5 involvement extends to immune response regulation and cell adhesion pathways. It interacts functionally with proteins like E-cadherin in these pathways which contribute to maintaining epithelial integrity. These pathways are critical for normal tissue maintenance and immune system function especially in mucosal surfaces where pathogen entry occurs. Understanding CEACAM5 interactions provides insight into cellular communication and adhesion mechanisms.
