Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Carcino Embryonic Antigen CEA antibody [EPR20721] - BSA and Azide free (ab229074)
Immunohistochemical analysis of paraffin-embedded human colon cancer tissue labeling Carcino Embryonic Antigen CEA with ab207718 at 1/40,000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Positive staining in human colon cancer (PMID: 25042385) is observed. Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).
Perform heat mediated antigen retrieval using ab93684 (Tris/EDTA buffer, pH 9.0).This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab207718).

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Carcino Embryonic Antigen CEA antibody [EPR20721] - BSA and Azide free (ab229074)
Immunohistochemical analysis of paraffin-embedded human spleen tissue labeling Carcino Embryonic Antigen CEA with ab207718 at 1/40,000 dilution, followed by a ready to use Goat Anti-Rabbit IgG H&L (HRP). Positive staining of spleen-infiltrating neutrophils (PMID: 22064717 and 19077207) is observed. Counter stained with Hematoxylin.
Secondary antibody only control: Used PBS instead of primary antibody, secondary antibody is a ready to use Goat Anti-Rabbit IgG H&L (HRP).

Immunocytochemistry/ Immunofluorescence - Anti-Carcino Embryonic Antigen CEA antibody [EPR20721] - BSA and Azide free (ab229074)
Immunofluorescent analysis of 100% methanol fixed MCF7 (human breast adenocarcinoma epithelial cell) cells labeling Carcino Embryonic Antigen CEA with ab207718 at 1/500 dilution, followed by Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) (ab150077) secondary antibody at 1/1000 dilution (green).
Confocal image showing membranous staining on MCF7 cell line.
Negative control for cells: PANC-1 .
Counterstained with ab195889 anti-alpha Tubulin antibody [DM1A] - Microtubule Marker (Alexa Fluor® 594) at a 1/200 dilution (red) and DAPI (blue).
The negative control is the secondary antibody only.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab207718).

Flow Cytometry - Anti-Carcino Embryonic Antigen CEA antibody [EPR20721] - BSA and Azide free (ab229074)
Flow cytometric analysis of PANC-1 (human pancreatic epithelioid carcinoma epithelial cell) (Left) / MCF7 (human breast adenocarcinoma epithelial cell) (Right) labeling Carcino Embryonic Antigen CEA with ab207718 at 1/500 (red) compared with a Rabbit monoclonal IgG (ab172730) (black) and an unlabeled control (cells without incubation with primary antibody and secondary antibody) (blue). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077), at 1/2000 dilution was used as the secondary antibody. Cells were not fixed or permeabilized. Gated on total viable cells.
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab207718).
