EPCAM and oropharynx squamous cell carcinoma: We tested the feline oropharyngeal squamous cell carcinoma cell lines, SCCF-2 and SCCF-3, as our model cells with R&D EpCAM-coated coverslips, using the rabbit monoclonal SB EpCAM antibody- and goat γ-globulin-coated coverslips as negative controls and fibronectin-coated coverslips as a control for integrin-mediated adhesion.
