Why is RNA sequencing better than microarray?

Transitioning from Arrays to RNA-Seq “mRNA-Seq offers improved specificity, so it’s better at detecting transcripts, and specifically isoforms, than microarrays. It’s also more sensitive in detecting differential expression and offers increased dynamic range.”

How does RNA-seq compare to microarray?

The main difference between RNA-Seq and microarrays is that the former allows for full sequencing of the whole transcriptome while the latter only profiles predefined transcripts/genes through hybridization.

Is RNA-seq cheaper than microarray?

In most cases, obtaining the expression profile of your sample would still be a bit cheaper using microarrays instead of RNA-sequencing, the difference being in the range of 50 to 100 EUR/USD per sample. However, the benefits of RNA-seq can easily outweigh the extra cost.

Why is RNA-Seq better than DNA seq?

Unlike DNA-seq, RNA-seq requires extracted RNA to be first reverse-transcribed into cDNA and then amplified. Most common applications of RNA sequencing are the detection of changes in gene expression, alternative splicing, post-transcriptional modifications, gene fusions as well as detection of mutations and SNPs.

Is RNA-Seq cheaper than microarray?

What is the purpose of RNA sequencing?

RNA-seq (RNA-sequencing) is a technique that can examine the quantity and sequences of RNA in a sample using next-generation sequencing (NGS). It analyzes the transcriptome, indicating which of the genes encoded in our DNA are turned on or off and to what extent.

Is RT PCR better than RNA-Seq?

While qRT-PCR is useful for quantifying the expression of a few genes, it can only detect known sequences. In contrast, RNA sequencing (RNA-Seq) using NGS can detect both known and novel transcripts. This broad dynamic range enables detection of subtle changes in expression, down to 10\%.
