3' mRNA-seq methods are generally cheaper per sample than standard bulk RNA-seq methods. [2] [7] [8] [9] This is because of the lower sequencing depth required due to only the 3' end of mRNA molecules being sequenced instead of the whole length of entire transcripts. Read depths of between one million and five million reads are recommended in ...
Rcount Rcount: simple and flexible RNA-Seq read counting. rDiff is a tool that can detect differential RNA processing (e.g. alternative splicing, polyadenylation or ribosome occupancy). RNASeqPower Calculating samples Size estimates for RNA Seq studies. R package version.
Long-read sequencing captures the full transcript and thus minimizes many of issues in estimating isoform abundance, like ambiguous read mapping. For short-read RNA-Seq, there are multiple methods to detect alternative splicing that can be classified into three main groups: [119] [91] [120]
RNA-Seq methodology has constantly improved, primarily through the development of DNA sequencing technologies to increase throughput, accuracy, and read length. [61] Since the first descriptions in 2006 and 2008, [ 40 ] [ 62 ] RNA-Seq has been rapidly adopted and overtook microarrays as the dominant transcriptomics technique in 2015.
Time-resolved RNA sequencing methods are applications of RNA-seq that allow for observations of RNA abundances over time in a biological sample or samples. Second-Generation DNA sequencing has enabled cost effective, high throughput and unbiased analysis of the transcriptome. [1] Normally, RNA-seq is only capable of capturing a snapshot of the ...
RNA Seq Experiment. The single-cell RNA-seq technique converts a population of RNAs to a library of cDNA fragments. These fragments are sequenced by high-throughput next generation sequencing techniques and the reads are mapped back to the reference genome, providing a count of the number of reads associated with each gene.

Small RNA sequencing (Small RNA-Seq) is a type of RNA sequencing based on the use of NGS technologies that allows to isolate and get information about noncoding RNA molecules in order to evaluate and discover new forms of small RNA and to predict their possible functions.
An RNA spike-in is an RNA transcript of known sequence and quantity used to calibrate measurements in RNA hybridization assays, such as DNA microarray experiments, RT-qPCR, and RNA-Seq. [ 1 ] A spike-in is designed to bind to a DNA molecule with a matching sequence , known as a control probe .
