Key Programs
-
Sample Preparation
Your provided cell pellets or tissue samples undergo rigorous preparation to ensure optimal results. This involves cell lysis, potentially further enrichment of ribosomes, and precise protein quantification. Proteins are then enzymatically digested into peptides using a highly efficient method like trypsinization, preparing them for MS analysis. The outcome is a high-quality peptide mixture ready for in-depth analysis. -
High-Resolution Analysis
The prepared peptide samples are subjected to liquid chromatography coupled with tandem LC-MS/MS. Utilizing DIA mode, the Astral system comprehensively fragments all parent ions within defined mass ranges, capturing an unparalleled depth of information. This step ensures high-throughput, sensitive, and reproducible data acquisition across all samples.
-
Data & Bioinformatics Analysis
The raw MS data is processed using advanced bioinformatics pipelines specifically designed for DIA datasets. This includes peptide and protein identification, label-free quantification, and robust statistical analysis to compare protein abundance across your experimental groups. Our sophisticated algorithms minimize missing values and ensure high quantitative accuracy.
-
Functional Analysis
Identified and quantified RPs are then subjected to in-depth functional annotation, pathway enrichment analysis, and protein-protein interaction studies. This provides a biological context for the proteomic changes observed, linking them to specific cellular processes, diseases, or regulatory networks.
-
Report GenerationUpon completion, you will receive a detailed report summarizing all experimental procedures, MS parameters, identified and quantified RPs, and a comprehensive bioinformatics analysis. This includes visual representations of your data, such as volcano plots, heatmaps, to facilitate understanding.
