Effects of PA on different cell lines expressing EpCAM. a EpCAM surface expression data assessed via flow cytometry using an Alexa Fluor 488-labeled anti-EpCAM mouse mAb (n = 3). Error bars reflect SEM. b Confocal imaging of stained Flp-In 293-EpCAM-BirA cells with PAwt-sANTXR-Ac2 and LFN-eGFP to assess PA oligomerization. c Viability assays for a set of cell lines with PAwt-sANTXR-Ac2, PAm-sANTXR-Ac2, PAm-Ac2, PAwt-Ac2, and PAwt (n = 3).
