Overcoming these challenges is critical to leverage the power of RNA-Seq for many biomedical applications. High throughput sequencing methods (bridge amplification, single molecular real time sequencing, and nanopore-based sequencing) have been widely applied in clinical settings but have had limited success for viral surveillance and aside from Flaviviruses (Zika virus, West Nile virus). We therefore subjected 5 pmol of purified RNA (26–30 nt in length, generated by RNAse I digestion) to sequencing library preparation using either the iCLIP2 protocol. The updates (listed below) do not in any way impact the protocols or. USD $2039. RNA sequencing is an increasingly preferred method for transcriptome analyses, and dependence of its results on input RNA integrity is of significant practical importance. 10. Use spike-in controls. For experiments that yield lower amounts of starting material, ultra-low input RNA sequencing may be a viable alternative. cDNA libraries were amplified using 17, 14, 10, or 7 PCR cycles for the 10 pg, 100 pg, 1 ng, or 10 ng libraries, respectively.
