Rna extraction from frozen cells
WebGeneral set up of the comparison The setup of this study is illustrated in Fig 1 and S1 Table. To assess the quantity and the qual-ity of RNA that could be extracted from PBMCs, we stored aliquots containing 106 PBMCs for two different time periods (1 day and 83 days) in five different storage media, i.e., (1) at 4 ˚C in RNAlater (RNL) or at -80 ˚C in (2) QIAzol … Web2.4 RNA Extraction. Total RNA is isolated using TRIzol reagent according to the manufacturer’s directions (Gibco-BRL). The procedure for solid tissues differs from that of blood or marrow mononuclear cells only in the first step.
