From: An RNA isolation system for plant tissues rich in secondary metabolites
Denaturing gel electrophoresis of RNA isolated from leaf tissues of rheum and arnebia: (A) before treatment with DNase, and (B) after treatment with DNase as detailed in the Methods section. RNA yield (μg/100 mg tissue) is mentioned above each panel, and A260/280 ratio is mentioned at the bottom of the panel. Clear 28 S and 18 S rRNA bands show integrity of the RNA.
