Primary Institution: RIKEN Yokohama Institute
Hypothesis
Can the CAGE-TSSchip accurately detect promoter-based transcriptional activity?
Conclusion
The CAGE-TSSchip is a fast and sensitive tool for promoter-based expression profiling that correlates well with traditional methods.
Supporting Evidence
- The CAGE-TSSchip showed good correlation with qRT-PCR results.
- It can identify the activity of each transcription start site.
- The method is faster and more cost-effective than deep sequencing.
Takeaway
The CAGE-TSSchip helps scientists see which parts of genes are active, making it easier to understand how genes work.
Methodology
The study developed a new labeling method for capped transcripts and used a customized oligonucleotide array to detect transcription start sites.
Limitations
The CAGE-TSSchip cannot identify novel promoters as it is based on known transcripts.
