protocol Protocol: Detection of Hydrogen Peroxide by DAB Staining in Arabidopsis Leaves
Hi,

Thanks for posting this protocol. I find this very helpful for my studies. However, I have following few questions:

1) I will be performing this assay with leaves of Arabidopsis seedlings (12-day old). In that case, which multiwell plate do you think would be best

Hi Fatima,
I recommend 12-well for Arabidipsis - any smaller will likely not be appropriate
I use pipettes for step 22 and replacing the bleach and de-stain solutions - it is easier and less likelihood of tissue damage
For storage, diluted destain solution is OK at 4C
Yes additional stabilization in water for 24 h is a good idea if you cut leaves. This is standard for leaf disc assays for example.
Good luck and let us know how it goes!
