RNA Library preparation kits for Illumina®
The transcriptome is the complete set of transcripts in a cell, and their quantity, for a specific developmental stage or physiological condition. Mainly including mRNA and non coding RNA.
Understanding the transcriptome is essential for interpreting the functional elements of the genome and revealing the molecular constituents of cells and tissues, and also for understanding development and disease.
RNA-Seq (RNA sequencing), also called whole transcriptome shotgun sequencing (WTSS), uses next-generation sequencing (NGS) to reveal the presence and quantity of RNA in a biological sample at a given moment in time.
RNA-Seq is used to analyze the continually changing cellular transcriptome. Specifically, RNA-Seq facilitates the ability to look at alternative gene spliced transcripts, post-transcriptional modifications, gene fusion, mutations/SNPs and changes in gene expression. In addition to mRNA transcripts, RNA-Seq can look at different populations of RNA to include total RNA, small RNA, such as miRNA, tRNA, and ribosomal profiling. RNA-Seq can also be used to determine exon/intron boundaries and verify or amend previously annotated 5' and 3' gene boundaries.
There are 2 types of RNA sequencing : RNA-Seq (whole transcriptome sequencing) and mRNA sequencing :
Whole Transcriptome Sequencing
RNA species of interest
All RNA transcripts >170 nt
Poly-A transcripts >170 nt
Coding or non-coding
Coding and non-coding transcripts
Ribosomal RNA depletion
Poly-A RNA selection
