The PR Reagent provides an easy 3-step method to isolate the total RNA from plant samples. This unique reagent system ensures the total RNA with a high yield and good quality from the most common plant samples as well as samples high in polysaccharides. If a larger sample is required, the kit volume can be scaled up proportionately, making the kit not only user-friendly but also highly versatile. The RNA phenol extraction is not required, and the entire procedure can be completed in 2 hours. The total RNA (up to 80 μg for fresh plant tissue) is ready for use in RT-PCR, Northern Blotting, cDNA Synthesis and Mapping.
