Methods Enzymol. 2013:530:337-43. doi: 10.1016/B978-0-12-420037-1.00019-1.


When working with RNA, the need often arises to concentrate a sample or purify it from various salts, nucleotides, and proteins. RNA precipitation is an easy and cost-effective method for the concentration of RNA, leaving a pellet that can be resuspended in the buffer of choice.
