Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CEACAM5 antibody [EPCEAR7] (AB133633)

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of Human gastric carcinoma tissue sections labeling Carcino Embryonic Antigen CEA with Purified ab133633 at 1 : 3000 dilution (0.6 μg/ml). Heat mediated antigen retrieval was performed using Perform heat mediated antigen retrieval using EDTA Buffer, PH9. Tissue was counterstained with Hematoxylin. ImmunoHistoProbe one step HRP Polymer (ready to use) secondary antibody was used at 1 : 0 dilution. PBS instead of the primary antibody was used as the negative control.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-CEACAM5 antibody [EPCEAR7] (AB133633)

Immunohistochemistry analysis of paraffin-embedded (A) HEK-293T cells transfected with a CEACAM1 expression vector containing a his tag, (B) HEK-293T cells transfected with a CEACAM3 expression vector containing a his tag, (C) HEK-293T cells transfected with a CEACAM5 expression vector containing a his tag, (D) HEK-293T cells transfected with a CEACAM6 expression vector containing a his tag, (E) HEK-293T cells transfected with a CEACAM8 expression vector containing a his tag and (F) HEK-293T cells transfected with empty vector containing a his tag, sections labelling Carcino Embryonic Antigen CEA with ab133633 at 1/2000 dilution. LeicaDS9800 (Bond™ Polymer Refine Detection) was used as the secondary antibody. Sections were counterstained with Hematoxylin. The section was incubated with ab133633 for 30 mins at room temperature. Heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0, epitope retrieval solution 2) for 20 mins. Positive staining on HEK-293T cells transfected with a CEACAM5 expression vector containing a his tag (Image C), and HEK-293T cells transfected with a CEACAM6 expression vector containing a his tag (Image D). No staining on other cell pellet tested. The immunostaining was performed on a Leica Biosystems BOND® RX instrument. IHC Note : ab133633 is also cross-reactIve with human CEACAM6 in IHC.

Immunocytochemistry/ Immunofluorescence - Anti-CEACAM5 antibody [EPCEAR7] (AB133633)

Confocal image showing membranous staining in MCF7 cell line.

Immunocytochemistry/Immunofluorescence analysis of MCF7 (human breast adenocarcinoma cell line) cells labelling carcino embryonic antigen (CEA) with ab133633 at 1/500. Cells were fixed with 4% paraformaldehyde and permeabilized with 0.1% Triton X-100. An Alexa Fluor^® 488-conjugated goat anti-rabbit IgG (ab150077) at 1/10000 dilution was used as the secondary antibody. The cells were counterstained with ab195889, a anti-alpha tubulin antibody at 1/200 dilution. DAPI was used as a nuclear counterstain.

Secondary antibody only control : Used PBS instead of primary antibody, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor^® 488) (ab150077) secondary antibody at 1/1000 dilution.

Western blot - Anti-CEACAM5 antibody [EPCEAR7] (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.

This antibody does not cross-react with human CEACAM1, CEACAM3, CEACAM6, and CEACAM8.

This blot was developed using a high sensitivity ECL substrate. The high-sensitivity ECL substrate used allows for the detection of proteins in the mid-femtogram range.
