I don't know about using it in gels, but I use to stain transferred RNA (and
DNA) on nylon membranes. I use 0.3% methylene blue in 0.3 M sodium acetate,
stain for 1 min, and destain with water. The staining solution can be reused
a lot of times.
All in all the Ponceau staining for nucleic acids!
hope this helps
