In today’s competitive and fast-moving drug discovery landscape, the ability to identify, validate, and prioritize the right biological targets is critical. Quantitative proteomics has emerged as a powerful engine driving this process, transforming complex biological data into actionable insights. At ITSI Biosciences, we are proud to support this transformation through over 21 years of bioanalytical expertise, innovative sample preparation products, and end-to-end proteomics services.
Why Quantitative Proteomics Matters in Drug Discovery
Drug discovery begins with understanding disease biology at the molecular level. While genomics and transcriptomics provide valuable information, proteins are the functional drivers of biological systems, and the direct targets of most therapeutics.
Quantitative proteomics enables researchers to:
- Measure protein abundance, dynamics, and modifications
- Compare disease vs. normal and control states with high precision
- Identify dysregulated pathways and actionable targets
- Validate targets through relative and absolute quantitation
By delivering accurate, reproducible protein-level data, quantitative proteomics shortens discovery timelines and reduces the risk of late-stage failure.
Accelerating Target Identification
ITSI Biosciences leverages advanced mass spectrometry-based proteomics to help researchers uncover novel and high-confidence drug targets. Using technologies such as:
- LC-MS/MS–based quantitative proteomics
- Tandem Mass Tag (TMT) multiplexing
- 2D-DIGE
- xMAP-based assays
We enable simultaneous comparison of multiple biological conditions, increasing statistical power while reducing cost and sample requirements.
Our expertise spans all sample types, including solid tissue, cells, blood, urine, plant material, and formalin-fixed paraffin-embedded (FFPE) tissue, allowing target discovery directly from clinically relevant samples.
Strengthening Target Validation with Precision
Identifying a target is only the beginning. Robust target validation is essential to confirm biological relevance and therapeutic potential. ITSI’s quantitative proteomics workflows support validation by:
- Providing relative and absolute protein quantitation
- Enabling pathway-level and network analysis
- Supporting biomarker discovery and verification
- Integrating proteomics data with experimental design and biological context
Our scientists work closely with clients to ensure that data is not only generated, but interpreted correctly, delivering meaningful insights that inform go/no-go decisions.
