Which Proteomic Service is Right for your Research? Taking you Beyond the Genome
Mapping protein expression and modifications that define biological processes to improve research outcomes.
Developing drugs in the post-genomic era faces new challenges to enable faster regulatory approval and development of protein based medicines. Proteome Sciences has developed an analytical proteomic pipeline to provide broad biological context of targets and drug mechanisms based on unbiased analysis of protein expression (TMT LC-MS2/LC-MS3, TMTcalibrator) and phosphorylation (SysQuant®), statistical bioinformatic packages including data modelling (FeaST) and a novel functional analysis tool (FAT).
TMT based LC-MS2 and SysQuant based proteomics are the perfect tools to support smarter target discovery and validation, characterization of disease models and determination of complete mechanisms of action.

Protein expression and regulation of pathway activity cannot be inferred from genomic or transcriptomic data but hold the key in understanding how new agents affect their targets and wider disease biology. Our specialized proteomics workflows can be applied across all aspects of drug development to deliver deeper insights, discover biomarker candidates and enable better decision making.
Measuring Proteins For Better Medicines
Specialised services to enhance discovery and validation of mechanistic biomarkers in peripheral fluids
Precision Medicine requires close integration between targeted drugs and biomarkers providing early and actionable clinical information. Ideally, such biomarkers are mechanistically related to disease and treatment mechanisms, predictive of outcome and measurable in accessible samples, typically body fluids.
For new biomarker discovery we have two key technologies to improve your chances of finding the most useful proteins in your sample matrix of choice. TMTcalibrator  combines protein and fluid proteomics to identify tissue proteins with evidenced availability for peripheral detection. If you only have fluid samples, using TMT LC-MS3 with abundant protein depletion improves quantitative accuracy over other proteomics methods. Irrespective of the analytical method, our suite of bioinformatics tools simplify discovery of new biomarker candidates.
If you already have candidate biomarkers at the protein or peptide level please see below to learn more about our range of targeted mass spectrometry solutions.
To aid selection of the right tool for your particular challenge we have set out the different classes of biomarker you may need, their intended use and our recommended service product.
