tiRNA & tRF Sequencing Service

IntegrateRNA has developed a high-throughput RNA sequencing platform, to investigate the biological functions of small noncoding RNAs of 16-45nt length, especially for tiRNAs and tRFs. We provide a comprehensive solution that covers total RNA preparation, tiRNA & tRF isolation and purification, library construction, sequencing and data analysis. Based on advanced NGS sequencing platform and data analysis pipeline, we assist in novel tiRNA & tRF discovery, mutation characterization, and expression profiling analysis of tiRNAs & tRFs.

tiRNAs (tRNA halves) and tRFs (tRNA-derived fragments) are a recent class of novel small RNAs derived from tRNA, ranging in length from 16 to 50 nt. tiRNAs & tRFs have been suggested to play roles in cell proliferation, priming of viral reverse transcriptases, regulation of gene expression, translation regulation, modulation of the DNA damage response, tumor suppression, and neurodegeneration. In addition, the composition and quantity of tRF & tiRNA are highly dependent on specific cell types and pathological conditions, making them an excellent biomarker with therapeutic potential. tiRNA & tRF sequencing is used to discover novel tiRNAs & tRFs, examine the differential expression of tiRNA & tRF and to characterize variations with single-base resolution.

Workflow of tiRNA & tRF Sequencing

tiRNA & tRF Sequencing Service

As shown, obtaining a premium RNA sequencing library begins with the isolation of tiRNA & tRF RNAs by size fractionation using gel electrophoresis selection or silica spin columns from total RNA. Following RNA adapter ligation using a 5’ adenylated DNA adapter with a blocked 3’end, small RNAs are reverse transcribed, amplified by PCR and sequenced. In order to maximize tiRNA & tRF sequence data quality, the PCR products are selected by gel purification.
