WebTo assess the effect of surfactants in RNA extractions from serum, BSA was supplemented into samples prior to RNA extraction. Fig. 5 presents the qRT-PCR results for samples supplemented with 0.03, 0.3 and 3% (w/v) BSA extracted using NS and 1, 2 and 3% (w/v) T100. Two-tailed t-tests (p < 0.05) were used to make comparisons between samples. WebMethods for quenching a nuclease digestion of a target nucleic acid prior to downstream analysis of the target nucleic acid are disclosed herein. Particularly, methods for controlling the end point of a nuclease digestion prior to sequence analysis of a target nucleic acid is provided. Quenching of a nuclease digestion in the present disclosure employs at least …
