CellROX Green

CellROX Green (Ex-Max 485 nm/Em-Max 520 nm)

CellROX® Green is a fluorogenic probe for measuring oxidative stress in live cells. The cell-permeant dye is weakly fluorescent while in a reduced state and exhibits bright green photostable fluorescence upon oxidation by reactive oxygen species (ROS) and subsequent binding to DNA, with absorption/emission maxima of ~ 485/520 nm. This reagent can be formaldehyde-fixed and its signal survives detergent treatment, which makes it able to be multiplexed with other compatible dyes and antibodies.
