Figure 1From: An RNA isolation system for plant tissues rich in secondary metabolitesDenaturing gel electrophoresis of RNA isolated from leaf tissues of rheum (A), and arnebia (B) using different RNA isolation methods viz. RNeasy®, TRIzol®, Guanidine-HCl, and IHBT protocol. RNA yield (μg/100 mg tissue) is mentioned above each panel, whereas A260/280 ratio is mentioned at the bottom of the panel. To ease comparison, equal volume of RNA (2 μl) was loaded. The starting material and the volume of the DEPC-treated water used to dissolve RNA were kept same in all the four procedures. N.D., not detectable.Back to article page
