Operational Workflow
-
Ribosome Isolation & Enrichment
For highly specific RP analysis, we offer optimized protocols for isolating ribosomes from the total proteome. This significantly enhances the signal-to-noise ratio for ribosomal phosphopeptides. -
Sample Preparation & Protein Extraction
Proteins are extracted from samples, followed by denaturation, reduction, and alkylation to prepare them for enzymatic digestion. This step ensures the integrity of the proteins and prepares them for subsequent analysis.
-
Phosphopeptide Enrichment
Due to the low stoichiometry of phosphorylation, phosphopeptides are enriched using advanced methods. This crucial step concentrates the target peptides, enabling their detection.
-
LC-MS/MS Analysis
Enriched phosphopeptides are separated by high-resolution liquid chromatography and analyzed using state-of-the-art mass spectrometry (MS) platforms. This identifies phosphopeptides and precisely localizes phosphorylation sites.
-
Bioinformatics & Data Interpretation
Raw MS data undergoes rigorous bioinformatics analysis, including phosphorylation site localization, differential phosphorylation analysis, motif analysis, and functional annotation, such as GO, KEGG pathway analysis. This translates complex data into meaningful biological insights.
-
Quality Control (QC) & ReportingRigorous QC inspections are conducted at each stage of the process. Subsequently, a detailed report is compiled, summarizing the outcomes and presenting all pertinent data.
