What is tRNA?

Transfer RNA (tRNA) is a small RNA molecule that plays a key role in protein synthesis. As the link between amino acids and nucleic acids, tRNA determines the genetic code.

Functions of tRNA

The functions of tRNAs have expanded beyond protein translation and include a large collection of roles in biosynthesis, viral replication, cellular stress responses and even animal behavior.

3. tRNA Microarray

In recent years, the development of microarray technology has promoted the study of tRNA expression. Microarrays analyze predefined transcripts/genes by hybridization, allowing simultaneous measurement of tens of thousands of tRNAs. BOC Sciences provides novel, straightforward and cost-effective tRNA microarray services to accurately measure tRNA abundance in a variety of biological samples. Our tailor-made methods exhibit excellent reproducibility, sensitivity, and specificity, all meeting or exceeding current standards for tRNA microarray analysis.

What we offer?

  • The absolute amounts of tRNA and tRNA charging levels
  • Identification of low-abundance species
  • Investigation of the biological relevance of changes in tRNA expression

4. tRNA Expression Analysis

Expression and mutation of tRNAs are closely related to certain diseases, including neuropathology and cancer development. Therefore, it is important to monitor and determine changes in tRNA abundance and modification during biological processes. tRNA gene expression has also received increasing attention, and scientists identify changes in tRNA expression by analyzing tRNA expression levels at the gene, codon, and amino acid levels.

BOC Sciences expression analysis tools

  • Classical reverse transcription-quantitative polymerase chain reaction (RT-qPCR): quantification of changes in individual tRNA abundance and analysis of tRNA expression patterns.
  • tRNA microarrays: determination of gene expression of tRNAs by identifying tRNA anticodon loops.
  • tRNA sequencing: assessment of differences in relative tRNA expression across treatments, tissues or subcellular fractions.

What we offer?

  • Expression profiles of tRNAs.
  • Identification of differentially expressed tRNAs.
  • Visualization of expression signatures of tRNAs.

5. tRNA Modification Analysis Service

Post-transcriptional modifications profoundly affect RNA structure and function. tRNAs are the class of RNA molecules with the largest number and types of modifications, and these modifications are associated with cancer and a range of diseases. Therefore, scientists have developed various tools and strategies to identify and quantify these important modifications. BOC Sciences offers mass spectrometry (MS)-based analysis services for comprehensive mapping of tRNA modifications. In addition to conventional LC-MS techniques, we also provide high-performance UPLC-MS and HPLC-MS analysis services, enabling rapid separation and identification of various modified ribonucleosides. Our method has high sensitivity and a broad quantitative range, which is suitable for analyzing tRNA modification patterns in a variety of cells.

6. tRNA Synthetase-Enzyme

tRNA synthetases are essential enzymes that provide fidelity to mRNA-to-protein translation in living cells by catalyzing the esterification of a specific cognate amino acid or its precursor to one of its compatible cognate tRNAs to form aminoacyl-tRNAs. tRNA synthetase plays an important role in DNA translation, gene expression, etc. In addition, it has impact on some metabolic and signaling pathways that are important for cell viability. BOC Sciences provides a wide variety of tRNA synthetases with different structures and functions to help you study potential drug targets for the treatment of various diseases.
