The ISOLATE II RNA Micro Clean-Up Kit is designed to purify and concentrate RNA, free from enzymatic inhibitors or any impurities. The optimised silica membrane technology and novel spin column design provides recovery of high-quality total RNA from 90 micro g down to nanogram amounts (Fig.1). The kit is well-suited for cleaning RNA from enzymatic reactions (e.g. DNase I digests, RNA labeling, in vitro transcription), or from phenol-purified RNA extracts (e.g. TRIsure
