mirVana miRNA Isolation Kit - Thermo Fisher Scientific
tools.thermofisher.comThe first step of the mirVana miRNA Isolation Kit procedure is to dis-rupt samples in a denaturing lysis buffer. Next, samples are subjected to Acid-Phenol:Chloroform extraction which provides a robust front-end purification that also removes most DNA (Chomczynski, 1987). Final RNA purification over glass-fiber filter
