a few days ago, I posted here to ask "how to check ROS levels in plants" and received a few replies. Thanks them. For those who also want to see the answers, posted as follows:
maybe you did alredy got your answer otherwise you could use DAB stainig.
is a Diaminobenidine sensitive to H2O2.

I can suggest you few ways:
-Fluorescence using a ROS-specific dye. I use H2DCFDA from invitrogen, in conjuction with fluorescence microscope or microplate fluorescence reader.

Hi Y Jiang,
There are few common staining methods that are use for several type ROS. H2O2 is normally the usual suspect in all stress conditions since it has the longest half life of all ROS types. Another ROS type is superoxide ions which are quickly dismutase to H2O2.
I attach here for you methods for both types - for H2O2: DCF-DA and DAB staining, for superoxid: NBT staining. I suggest you try to stain H2O2 because it is the easiest and usually it is sufficient.
