tRNA Sequencing Service

IntegrateRNA has introduced the most advanced tRNA-seq method that integrates optimized tRNA modification removal and small RNA sequencing to ensure maximum reliability of sequencing data. We offer sample-to-data analysis service accurately profile tRNAs and sensitively detect tRNA mutations, tRNA variants and tRNA isoforms. Based on highly experienced scientists execute quality management, IntegrateRNA also provides rigorous data quality control and a wealth of tRNA bioinformatics analysis to facilitate tRNA discovery and profiling.

Transfer RNA (tRNA) is a small RNA molecule involved in a wide variety of biology processes including cell survival, cell proliferation, cell differentiation, metabolism of amino acids, and cell signaling, stress response program and HIV-1 priming. High-throughput RNA-sequencing has provided insight into the importance of small RNAs in a wide range of biological contexts. However, significant obstacles for the sequencing of tRNA include the presence of numerous post-transcriptional modifications and its stable and extensive secondary structure, which interfere with cDNA synthesis and adaptor ligation. Recently, IntegrateRNA has introduced unique ARM-seq technology (Figure 1) for efficient and quantitative tRNA sequencing.
