What is RNA-Seq and how does it work?
In addition to polyadenylated messenger RNA (mRNA) transcripts, RNA-Seq can be applied to investigate different populations of RNA, including total RNA, pre-mRNA, and noncoding RNA, such as microRNA and long ncRNA. This article provides an introduction to RNA-Seq methods, including applications, experimental design, and technical challenges.How can ont direct RNA-Seq be used for differential expression?
How can ont direct RNA-Seq be used for differential expression?Recent uses of ONT direct RNA-Seq for differential expression in human cell populations have demonstrated that this technology can overcome many limitations of short and long cDNA sequencing. Standard methods such as microarrays and standard bulk RNA-Seq analysis analyze the expression of RNAs from large populations of cells.
Which RNA-seq method has the highest error rate?
Which RNA-seq method has the highest error rate?Traditionally, single-molecule RNA-Seq methods have higher error rates compared to short-read sequencing, but newer methods like ONT direct RNA-Seq limit errors by avoiding fragmentation and cDNA conversion.
What are the experimental design considerations for RNA sequencing?
Common experimental design considerations include deciding on the sequencing length, sequencing depth, use of single versus paired-end sequencing, number of replicates, multiplexing, randomization, and spike-ins. When sequencing RNA other than mRNA, the library preparation is modified.How can I check the integrity of total RNA?
How can I check the integrity of total RNA?The integrity and size distribution of total RNA can be checked by electrophoresis on a denaturing agarose gel and staining with ethidium bromide. The ribosomal RNA bands should appear as sharp bands on the stained gel.
What should be the rin value of RNA for RNA sequencing?
What should be the rin value of RNA for RNA sequencing?The RNA sample should have a RIN value higher than 7. The integrity and size distribution of total RNA can be checked by electrophoresis on a denaturing agarose gel and staining with ethidium bromide. The ribosomal RNA bands should appear as sharp bands on the stained gel.
