Ribosomal Transcriptome Analysis Services
Are you struggling to grasp the nuances of gene regulation beyond mere mRNA abundance, pinpoint actively translated drug targets, or unravel the intricate translational dynamics underlying disease mechanisms? Our ribosomal transcriptome analysis services help you accurately quantify protein synthesis and uncover novel biological insights through state-of-the-art techniques and comprehensive bioinformatics.
Introduction of Ribosomal Transcriptome Analysis Services
Ribosomal transcriptome analysis, primarily through ribosome profiling (Ribo-seq), offers a powerful lens into the dynamic process of protein synthesis. Unlike traditional RNA sequencing, which measures mRNA abundance, Ribo-seq quantifies active translation by sequencing mRNA fragments protected by ribosomes. This direct measurement of ribosome occupancy provides critical information on which genes are truly being expressed as proteins, their translation rates, and the precise regions being translated, including non-canonical ORFs. This methodology has revolutionized our understanding of gene regulation, revealing complex layers of translational control in health and disease.

Service Procedures
Our streamlined and robust workflow ensures high-quality data and comprehensive analysis for your ribosomal transcriptome projects.
-
Project Consultation & Design
Collaborative discussion to understand your research goals, select appropriate methodologies, and define project scope. -
Sample Quality Control (QC)
Rigorous assessment of incoming samples (e.g., RNA integrity, concentration) to ensure suitability for Ribo-seq.
-
Ribosome Footprint Generation
Cells or tissues are lysed under conditions that preserve ribosome-mRNA complexes. Unprotected mRNA is digested by nucleases, leaving ribosome-protected fragments (RPFs).
-
Library Construction & QC
RPFs are converted into a cDNA library suitable for next-generation sequencing (NGS), including adapter ligation and size selection. Library quality and concentration are assessed.
-
Next-Generation Sequencing
Libraries are sequenced on advanced NGS platforms to generate high-throughput RPF reads.
-
Bioinformatics Analysis & InterpretationRaw data undergoes rigorous QC, reads are aligned to the reference genome/transcriptome, and ribosome occupancy is quantified. The analysis includes the identification of translated ORFs, differential translation analysis, codon occupancy, and more.
Final Deliverables
- A detailed project report summarizing the methodology, QC results, data analysis, and key findings, including publication-ready figures and tables.
- Processed data files: Raw sequencing data (FASTQ), aligned reads, gene/transcript translation level quantification, and lists of differentially translated genes.
- Custom analyses and visualizations as discussed during project design.

FAQs
Q: How does it differ from standard RNA-Seq?
A: While RNA-Seq measures RNA abundance, ribosomal transcriptome analysis pinpoints actively translated mRNA regions, offering a direct view of protein synthesis and uncovering translational controls invisible to RNA-Seq alone. Combining both methods provides a complete picture of gene expression.
Q: What biological questions can your ribosomal transcriptome analysis service address?
A: Our service helps identify actively translated genes, quantify translation changes under stress/drug treatment, discover novel ORFs, map translation initiation sites, and analyze ribosome pausing.
Q: Why choose our ribosomal transcriptome analysis service over in-house setups?
A: We provide optimized protocols, expert-led sequencing, and advanced bioinformatics, saving time on troubleshooting and ensuring high-quality, insightful data often more efficiently than building infrastructure independently.
Q: What sample preparation steps are critical?
A: Flash-freeze samples immediately, ship them on dry ice and use RNase inhibitors during collection to prevent degradation. We supply detailed guidelines tailored to your sample type.
Q: Can Ribo-seq data integrate with other omics data?
A: Absolutely! Combining Ribo-seq with RNA-Seq, proteomic, or epigenomic data reveals systems-level gene regulation. Our team assists with multi-omics analysis to deepen insights.
