Viability of J774.2 cells is not affected by DEP exposure. J774.2 macrophages were treated for 2 hours with either DEPs (left, middle) or sham-treated (right) and stained with Trypan blue to confirm that DEP exposure does not affect viability of cells. Dye is taken up by a minority of cells (closed arrows), which indicates cell death. DEP uptake by J774.2 macrophages is also visible (open arrows). Scale bars represent 10 microns.
