Recovery of Purified RNA Extraction and purification of RNA are required for numerous downstream molecular biology applications such as RT-PCR, qPCR, Western blotting, and RNA amplification. Porvair Sciences has launched the kits for rapid extraction of total RNA from a wide range of biological samples called the Chromatrap RNA Extraction Kit. The company claims the kit enables the extraction of up to 1000 µg of application-ready pure RNA in as little as 10 minutes. The kit was designed to allow scientists to process up to 107 cultured animal cells, 50 mg animal tissue, 0.5 mL blood, 250 mg plant material, 5 x 107 yeasts, or 5 x 108 bacteria in a single go.
