WebMicro Kit in duplicates (for each kit). Yield was determined by using a NanoDrop 8000 Spectrophotometer (Figure 1). The average RNA yields obtained from 1 x 107 and 1 x 106 PBMC were 6.29 µg and 0.29 µg RNA with the RNeasy Mini and RNeasy Micro protocols, respectively. To control the integrity and overall quality of the RNA eluates, samples WebApr 1, 2013 · RNA quality and quantity were both significantly (p < 1 × 10 –5) higher in buffy coat samples thawed in the presence of RNAlater as compared with Qiazol (RIN: 7.17 ± … don\\u0027s world of sports palos hills il
RNA isolation from frozen buffy coat in RNAlater?
WebThe LeukoLOCK™ Total RNA Isolation System can also be used to isolate WBCs for extraction, by using a proprietary filter to retain WBCs (that allows RBCs to pass through). RNA can be extracted directly from the buffy coat fraction, using standard methods such as TRIzol® reagent, RNAqueous® kits, or the mirVana™ miRNA Isolation Kit. WebQIAsymphony magnetic particles may copurify RNA if it is present in the sample. In order to minimize RNA content in the sample, add RNase A to the sample before starting the procedure. The final RNase A concentration should be 2 mg/ml. Buffy coat Buffy coat is a leukocyte-enriched fraction of whole blood.
