What Is RNA/Transcriptome Sequencing?
What Is a Transcriptome?
A transcriptome is a collection of all the transcripts present in a given cell. An RNA sequence mirrors the sequence of the DNA from which it was transcribed, so by analyzing the entire collection of RNAs or transcriptomes in a cell, researchers can determine when and where each gene is turned on or off in the cells and tissues of an organism.
Why Is Transcriptome Sequencing Important?
RNA sequencing gives researchers more visibility into previously undetected changes that occur in certain states of diseases. Using RNA sequencing, researchers can learn more about a transcriptome’s new and existing qualities in just one assessment. They can also see how a transcriptome reacts to certain therapies, environmental situations, and other conditions. RNA sequencing even reveals alternative gene-spliced transcripts, gene fusion, mutations and variants, post-transcriptional modifications, and other gene expressions.
As DNA sequencing technology advances, RNA/transcriptome sequencing becomes more affordable and widely available. This has made RNA sequencing an excellent tool for RNA editing, RNA profiling, and allele-specific expression.
Types of RNA/Transcriptome Sequencing
Science utilizes many different methods of RNA and transcriptome sequencing to identify existing and novel types of gene expression. At Psomagen Inc., we use only the most advanced and industry-standard methods, including the following:
- mRNA Sequencing: This type of RNA sequencing is one of the most popular methods of analyzing disease states and biological processes in the study of transcriptomes. This method is extremely in-depth and allows researchers to find new genes that were previously imperceptible.
- Small RNA Sequencing: This type of sequencing targets and isolates small RNA, including microRNA, to discover how noncoding RNA affects different types of gene expressions.
- Whole RNA Sequencing: Whole RNA sequencing is a comprehensive method that aims to accurately measure the number of genes and transcripts in the transcriptome. It identifies existing and novel coding and noncoding RNA.
- Targeted RNA Sequencing: This sequencing method focuses on two different types of targeted transcriptome assessment: targeted enrichment and targeted amplicon.
- RNA Exome Capture Sequencing: This method of RNA sequencing identifies different types of RNA exomes by examining specific regions of RNA coding.
- Single-Cell RNA Sequencing: This type of RNA sequencing studies individual cells, specifically the transcriptomes and genomes. It allows researchers to examine the small complexities of each region of a transcriptome.
Benefits of RNA/Transcriptome Sequencing
Because this form of sequencing does not require prior knowledge about the transcript, it can identify information that might be overlooked by other methods. Some of its benefits include:
- The ability to capture both previously known and novel transcriptome features
- Close, accurate studies of a variety of gene expression
- Reliable results — often at a lower price point per sample
RNA sequencing is precise in measuring transcripts and identifying complexities. It can more accurately determine gene expressions than many other methods of arrays.
How Psomagen’s RNA/Transcriptome Sequencing Services Work
Psomagen Inc. RNA/transcriptome sequencing services include the following:

We take great care of your samples from beginning to end, regardless of which of our services you use. Our expert lab staff ensures quality results by adhering to strict quality assurance processes. Learn a little more about our RNA sequencing workflow here:
Sample preparation:
Before RNA can be sequenced, the sample must be fragmented for next-generation sequencing (NGS).
Library preparation:
The next step involves attaching adapters to the ends of the fragments, such as the primary sequencing site and the amplification element, to make sequencing possible.
Sequencing:
Using NGS, the library can be sequenced. The extent of the library sequencing depends on what the data will be used for.
Raw data output and bioinformatics analysis:
In the last step, researchers conduct an RNA sequencing analysis to identify genes that are expressed in a unique way based on environment, biological factors, and more and draw hypotheses from the evidence.
