RNA Extraction by the Proteinase K Method

  • Protocol

Part of the book series: Methods in Molecular Biology ((MIMB,volume 2))

Abstract

This method of RNA extraction relies on a relatively gentle lysis procedure that should burst the cells, but leave the nuclei intact. Contamination of a relatively RNase-free cytoplasmic environment with nuclear nucleases is thus minimised. Next the polysomes are dissociated with SDS and proteinase K and finally the protein is removed by several phenol/choloroform extractions (1,2).
