From: Canine distemper virus induces apoptosis in cervical tumor derived cell lines
Flow-Cytometry histogram: Subdiploid DNA content was assessed by staining with PI and flow cytometry analysis. CDV infection induces apoptosis in HeLa cells (B). Cisplatin, positive control is demonstrated to cause apoptosis in positive control group (C). Negative control did not show subdiploid DNA content (A). Subdiploid DNA content indicates DNA fragmentation, typical in apoptotic cells.
