- 08:32Results: Quantification of the Abundance and Charging Levels of tRNAs
- 09:59Conclusion
Here we present a method for directly measuring transfer RNA charging levels from purified Escherichia coli RNA as well as a way to compare relative levels of transfer RNA, or any other short RNA, across different samples based on the addition of spike-in cells expressing a reference gene.
