Se-Immunoconjugates induced no apoptosis in HME50-5E Cells. (a) Sutent (apoptosis control), (b) 0.1% Triton X-100 (necrosis) control), (c) Control untreated, (d) Selenite, (e) Bevacizumab, (f) Selenobevacizumab, (g) Trastuzumab, (h) Selenotrastuzumab treatments in HME50-5E cells. HME50-5E cells were stained with Annexin V/PI Mitotracker Red and subjected to flow cytometric analysis. The four quadrants represent—living cells (Upper Left; UL: Annexin V, Mitotracker Red), early apoptotic (Upper Right; UR: Annexin V, Mitotracker Red), late apoptotic (Lower Right; LR: Annexin V, Mitotracker Red) or necrotic (Lower Left; LL: Annexin V, Mitotracker Red) stages.
