Skills
Non-exhaustive list of services offered by the Bordeaux Proteome Platform.
For other types of applications, please contact the platform manager, Caroline Tokarski.
Sample preparation for Mass Spectrometry analysis
- Electrophoretic or chromatographic separation of proteins/peptides (SDS-PAGE, 2D-PAGE, OffGel, GelFree, C18, C4, SEC, IEX, monolithic…).
- Enrichment/depletion of proteins/peptides (sera analysis, plasmas, etc.).
- Enrichment of peptide subspecies (phosphoproteomics, glycosylation…).
- Proteolysis adapted to the sample and the analysis (in gel, en solution, stratégie multi-enzymatique, échantillons à l’état de traces …).
Analysis of proteins/peptides by High Resolution Mass Spectrometry
- Identification of proteins in complex mixtures.
- Characterization of proteins: measurement of molecular mass, identification and localization of co/post-translational modifications (phosphorylation, glycosylation, ubiquitination, etc.).
- de novo sequencing (no database comparsion) de novo de protéines.
- Protein de novo sequencing
- Differential expression proteomics with labeling (SILAC, TMT) or without labeling (Label-free).
Bio-informatics data processing
- Reprocessing of mass spectrometry data for the identification, characterization and quantification of proteins using dedicated software.
- Partnership with the Bordeaux Bioinformatics Center for the analysis and integration of omics data: statistical validation, enrichment in GO terms, tools for visualization and interpretation of results, functional annotation of proteomes.
R&D expertises
- Structural analysis of proteins by isotopic exchange or cross-linking: conformational study, protein-protein interactions, epitope mapping, etc.
- Imaging by MALDI-Orbitrap mass spectrometry: identification and localization of lipids, metabolites, peptides/proteins (in situ digestion)…
- Structural analysis of proteins by isotopic exchange or cross-linking: conformational study, protein-protein interactions, epitope mapping, etc.
- Top-down proteomic analysis: identification of intact proteins and their post-translational or chemical modifications, identification of protein variants, identification of cleaved protein forms in situ.
- Analysis of glycoproteins/glycopeptides: identification and localization of N- and O-glycosylations
- Trace and ultra-trace analysis in the field of cultural heritage: identification of proteins, lipids and sugars, chemical/post-translational modifications, original biological species from different types of ancient materials.
