BULK RNA SEQUENCING
A powerful technique for uncovering the transcriptional profile of a pool of cells.
BULK RNA SEQUENCING
Bulk RNA sequencing is useful for the identification of transcripts in an isolated sample.
Highlights
- Bulk RNA sequencing (RNA-seq) is the identification of transcripts in an isolated sample.
- RNA-seq offers in depth discoveries of differentially expressed genes between two or more conditions.
- The technique is applicable to both eukaryotic and bacterial samples.
When to use Bulk RNA sequencing?
To unravel various biological systems, it is essential to understand the complexity of transcriptomic changes. Bulk RNA sequencing serves to obtain a high-throughput representation of average transcriptomic changes between two or more conditions. Depending on the type of samples, you can use bulk RNA sequencing in:
Sample type: BACTERIA
- Targets for drug and vaccine development(1)
- Antibiotic resistance(2)
- Infection diseases and virulence(3)
- Synthesis of biomolecules for industrial use (exoenzymes, antioxidants, etc.)(4)
- Metabolic activities of microbes that provide nutrients to crops (5)
Sample type: HUMAN BIOPSIES and ANIMAL MODELS
- Identification of diferentially expressed genes, uncover underlying pathways and network analysis.
- “Deconvolution” to cell type atlases to quantify the cell type composition in the sample (6).
- Analysis of alternative splicing
- Biomarker discovery (7)
Do you want to investigate splice variants using Bulk RNA sequencing?
When investigating splice variants, sequencing deeper is typically recommended(8). In principle, we can sequence as deep as necessary, and this will be a topic that is always discussed in the introduction consultation.
