Proteomics Analytical Services

Proteomics Analytical Services

Proteomics can help early discovery teams identify and validate drug targets, uncover critical biomarkers for pharmacology groups, determine on- and off-target effects, and the mechanism of action during the development process. Not a proteomics expert? You don’t have to be. As an innovator in proteomics discovery for over 20 years and inventor of PTMScan® Technology, CST has the deep scientific expertise to take on your most complex proteomics projects.

Consultative Approach

On-Time Answers

Our fast, reliable timelines* for proteomics results give you the actionable information needed to make informative decisions quickly to keep projects on track. Our scientists work with you to understand your goals and provide guidance on service options and experimental design, to make sure the results are meaningful and advance your discovery research efforts.

Actionable Data and Analysis

Comprehensive Coverage

CST provides the most comprehensive suite of proteomics services to probe mechanistic cell biology and guide translational research. This encompasses total protein profiling and 20 most critical types of post-translational modifications (PTMs), with more in the pipeline. Thorough quantitative proteomics and bioinformatic results are organized with expert analysis to deliver mechanistic insight in an easy-to-understand data package. Statistically relevant differences are highlighted, so there’s no guesswork and you can confidently identify critical biomarkers from your model study.

*Specific project timelines vary depending on the complexity and size of the service project.

Demystifying Proteomics

A limited number of genes can generate a tremendous level of complexity at the protein level due to processes such as alternative splicing and posttranslational modification.

PTMs are essential for many cellular functions like protein activity, subcellular localization, degradation, and protein-protein interactions.

Bio-analytical applications that probe both a wide range of PTMs and global changes in protein levels provide insight into both normal and disease-based biology otherwise not feasible at the genetic level. A holistic proteomic analysis can also provide critical information to accelerate drug development efforts by identifying specific biomarkers for early disease progression or as indicators for drug efficacy or dosing.
