There are a couple fluorescent probes that recognize reactive oxygen
species, i.e. hydroethidine and dichlorofluorescein diacetate. Their
specificity for superoxide vs. peroxide has been questioned, though. It
seems to me that a protocol could be developed using these probes.
Check out Meth. Cell Biol., volume 41, chapter 28 for more details.
