Ribosomal Modification Proteomic Analysis Services
Our Capabilities
Are you currently grappling with challenges such as dissecting intricate protein interactions, decoding obscure disease mechanisms, or discovering new biomarkers? At Creative Biolabs, our ribosomal modification proteomic analysis services are thoughtfully crafted to offer precise and actionable insights into the dynamic realm of ribosomal proteins (RPs) modifications. We excel in identifying novel post-translational modifications (PTMs) on RPs, accurately quantifying alterations in their modification levels across diverse experimental conditions, and precisely mapping the specific modification sites. Our ribosomal modification proteomic analysis services empower you to unravel complex cellular pathways, pinpoint novel therapeutic targets, and obtain unparalleled insights into biological processes by leveraging cutting-edge mass spectrometry and bioinformatics platforms.
Introduction of Ribosomal Modification Proteomic Analysis Services
RPs, historically viewed as static structural components, are now recognized as dynamic entities undergoing extensive PTMs. These modifications play pivotal roles in regulating ribosome biogenesis, fine-tuning translation fidelity, and orchestrating cellular stress responses, profoundly impacting cell fate and disease pathogenesis. Recent studies increasingly highlight the critical involvement of ribosomal PTMs in diverse biological processes, ranging from cancer development and progression to neurodegeneration and metabolic disorders. Understanding these intricate modifications is therefore paramount for unlocking novel therapeutic strategies, identifying robust diagnostic biomarkers, and gaining a deeper comprehension of fundamental cellular biology. Our services provide the advanced tools and expertise to precisely map and quantify these crucial ribosomal modifications.

Operational Flow
-
Sample Preparation & Digestion
Proteins are meticulously extracted from the provided samples, and if necessary, further purified to enrich for RPs. They then undergo reduction and alkylation to prepare them for enzymatic digestion. Finally, the proteins are enzymatically digested into smaller peptides using highly specific proteases. -
PTM Enrichment
For low-abundance modifications or to enhance detection sensitivity, specific enrichment strategies are employed. This can include immunoaffinity purification using PTM-specific antibodies or chromatographic methods for enrichment of phosphorylated peptides.
-
LC-MS/MS Analysis
Enriched peptides are separated by high-performance LC, which resolves them based on their physicochemical properties. The separated peptides are then introduced into a state-of-the-art MS/MS. The mass spectrometer measures the mass-to-charge ratio of the peptides and generates fragmentation data for identification.
-
Data Processing & Database Searching
The raw MS data is processed using advanced bioinformatics software to convert it into a searchable format. These processed spectra are then searched against comprehensive protein databases using specialized algorithms to identify the peptides and, crucially, their specific modification sites based on mass shifts.
-
Bioinformatics & Statistical AnalysisIdentified PTMs are rigorously quantified across different samples, and statistical analyses are performed to determine significant changes in modification levels. This data is then integrated with various biological pathways and functional annotation databases to provide deeper insights into the biological roles of the identified modifications.
