Download scientific diagram | NO 2 , ONOO , or the ONOO generator, 3-morpholinosydnonimine (SIN-1) selectively kill log phase lung epithelial cells. (A ) A line of rat alveolar Type II epithelial cells (21) was used and grown to log phase or confluence and exposed to 5 ppm of NO 2 for 4 hours, and cell death was assessed immediately or 4, 24, 48 or 72 hours after cessation of exposure. (B ) Log phase or confluent rat alveolar Type II epithelial cells cells were exposed to 1 mM ONOO or 1 mM SIN-1 and death was assessed after 2, 4, and 24 hours. Cell death was assessed using an antibody recognizing single-stranded DNA (17), and results are expressed at the percentage of APOPTAG positive cells.
