Human colon carcinoma cell line HT29 stained with purified 9C4, followed by anti-mouse IgG FITC -
BT474 breast cancer cells were stained with anti-human CD326 (clone 9C4) using 1:100 dilution, followed by DyLight™ 649 anti-mouse Ig secondary antibody (red) plus DAPI staining for nuclei (blue). Cells were fixed with 4% PFA, permeabilized with 0.1% Triton X-100, blocked with 10% serum, and incubated O/N at 4°C. Images were taken under 20x (filter set: EX 647/10x, Dichroic 665LP, EM 700/70x) at exposure 4s. Data provided by John Nolan and Er Liu, La Jolla Bioengineering Institute.

CD326 is also known as Ep-CAM, tumor associated calcium signal transducer 1, epithelial cell surface antigen, epithelial glycoprotein 2, EGP2, adenocarcinoma associated antigen, and TROP1. CD326 is a type I transmembrane protein containing six disulfide bridges and one THYRO domain. This cell surface glycosylated 40 kD protein is highly expressed in bone marrow, colon, lung, and most normal epithelial cells and is expressed on carcinomas of gastrointestinal origin. Recently, it has been reported that CD326 expression occurs during the early steps of erythrogenesis. CD326 functions as a homotypic calcium-independent cell adhesion molecule and is believed to be involved in carcinogenesis by its ability to induce genes involved in cellular metabolism and proliferation. CD326 antigen is an immunotherapeutic target for the treatment of human carcinomas.
