Any research project that ostensibly starts with a sample of purified RNA—such as RNA-seq and RT-PCR—inevitably begins earlier, with the process of obtaining the RNA from tissue or isolated cells. But extracting and purifying RNA from that important starting sample is no easy task. RNA is an unstable molecule that easily degrades unless care is taken to preserve it during the process of extraction. Further purification removes contaminants, DNA, and other unwanted molecules to obtain high-quality RNA samples needed for the best results in downstream applications. This article looks at optimized reagents, kits, and workstations that researchers rely on to streamline workflows for RNA extraction and purification.
