Tempol blunts 15d-PGJ2-induced ROS levels in HL-1 cardiomyocytes.
By Chintan Koyani on 10/13/2018
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: HL-1 cardiomyocytes

HL-1 cardiomyocytes were incubated with Tempol (1 mM) for 30 min prior to 15d-PGJ2 treatments (15 μM) for 1 h to follow ROS generation using carboxy-H2DCFDA (10 μM). Figure shows that the antioxidant Tempol (a cell-permeable superoxide anion scavenger) blunted 15d-PGJ2-induced ROS formation efficiently.
