Flow cytometric analysis of DNA fragmentation. Untreated FI cells (A) and FI cells treated with 1 mM H₂O₂ for 2 h (B) or 24 h (C) were subjected to flow cytometric analysis. FI cells were infected with HSV-1 at an MOI of 2 PFU/cell and cultured for 20 h (D). HSV-1-infected cells were treated with 1 mM H₂O₂ from 18 to 20 h p.i. (E) or from 18 to 42 h p.i. (F). These infected cells were also subjected to flow cytometric analysis.
