Our ribosome profiling service offers an unparalleled view into the dynamic world of protein synthesis. Are you grappling with understanding true gene expression beyond simple mRNA abundance, identifying novel drug targets missed by transcriptomics alone, or deciphering complex translational regulatory networks? Our ribosome profiling service helps you gain unprecedented insights into active protein synthesis and translational control through advanced next-generation sequencing of ribosome-protected mRNA fragments and sophisticated, customized bioinformatics analysis, empowering your research development.
Ribosome profiling, or Ribo-seq, is a powerful technique that provides a "snapshot" of all ribosomes actively translating mRNA in a cell at a specific moment. By sequencing the mRNA fragments protected by these ribosomes, researchers can quantitatively measure gene expression at the translational level, identify the exact regions of mRNA being translated (including novel ORFs), and assess the efficiency of protein synthesis on a genome-wide scale. This method offers deeper insights than transcriptomics alone, revealing crucial regulatory mechanisms that control protein production and cellular function.

A: RNA-Seq measures the abundance of mRNA transcripts, indicating which genes are transcribed. Ribosome profiling, however, directly measures active translation by sequencing only those mRNA fragments actively occupied by ribosomes. Choose ribosome profiling when you need to understand post-transcriptional gene regulation, identify actively translated ORFs, assess translational efficiency, or study the mechanism of drugs affecting protein synthesis.
A: Ribosome profiling is versatile and can address numerous questions, such as: Which genes change their protein synthesis rates under stress or drug treatment? Are there alternative translation start sites being used? Are non-coding RNAs being translated? How does ribosome occupancy change during different cell cycle stages or developmental processes? It's invaluable for drug discovery, understanding disease mechanisms, and fundamental biology.
A: Yes! Ribosome profiling quantifies translational efficiency by comparing ribosome density to mRNA levels, detects ribosome stalls via localized RPF pileups, and identifies frameshifting by analyzing codon-by-codon triplet periodicity deviations.
At Creative Biolabs, our ribosome profiling service empowers researchers to delve deeper into the complexities of gene expression by providing a direct and quantitative measure of protein synthesis.
