Human paraffin-embedded spleen tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Citrate buffer 1X pH 6.0 at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL of anti-human CD66a/c/e (clone ASL-32) Spark YG™ 570 (red) at 4°C overnight. Nuclei were counterstained with DAPI (blue).

Human paraffin-embedded colon tissue slices were prepared with a standard protocol of deparaffinization and rehydration. Antigen retrieval was done with Citrate buffer 1X pH 6.0 at 95°C for 40 minutes. Tissue was washed with PBS/0.05% Tween 20 twice for five minutes and blocked with 5% FBS and 0.2% gelatin for 30 minutes. Then, the tissue was stained with 10 µg/mL of anti-human CD66a/c/e (clone ASL-32) Spark YG™ 570 (red) and anti-Pan-Cytokeratin (clone C-11) Alexa Fluor® 488 antibody (green) at 4°C overnight. Nuclei were counterstained with DAPI (blue). The image was scanned with a 10X objective and stitched with software.
Human colorectal adenocarcinoma cell line HT-29 was stained with anti-human CD66a/c/e (clone ASL-32) Spark YG™ 570 (filled histogram) or mouse IgG2b, κ isotype control (open histogram).
The ASL-32 mAb reacts with an antigen epitope shared by CD66a, c and e. CD66a/c/e are members of the CEA (carcinoembryonic antigen) family of the Ig superfamily. CD66 plays a role in hemophilic and heterophilic adhesion. CD66a, also known as CEACAM1 and BGP (biliary glycoprotein), is mainly expressed on granulocytes, binds to CD66a, c, e, and CD62E. CD66c (known as CEACAM6, NCA) is expressed on granulocytes and epithelial cells. The ligands of CD66c are CD66a-e, CD62E and Galectins. CD66e molecule is also called CEA or CEACAM5, and is primarily found on epithelial cells. CD66e binds to CD66a, c and e.
Each lot of this antibody is quality control tested by formalin-fixed paraffin-embedded immunohistochemical staining. For immunohistochemistry, a concentration range of 5 - 10 µg/mL is suggested. For flow cytometric staining, the suggested use of this reagent is ≤ 0.5 µg per million cells in 100 µL volume. It is recommended that the reagent be titrated for optimal performance for each application.
* Spark YG™ 570 has a maximum excitation of 555 nm and a maximum emission of 570 nm.
