MASS SPECTROSCOPY FOR DISCOVERY & GROWTH
Proteomics & Bioanalysis
Located on the Buffalo Niagara Medical Campus, UB's Proteomics and Bioanalysis Core specializes in proteomics, PK/PD, lipidomics, metabolomics and biopharmaceutical analysis. The Core is a resource for UB researchers and regional investigators, providing state-of-the-art instrumentation and expertise in proteomics and bioanalysis. We assist companies of all sizes, from startups to Fortune 500, with programs tailored to fit their needs. Partners trust our services from concept to completion.
Specializing in proteomics, liquid chromatography, mass spectrometry and bioinformatics
Whether your project is large or small, we help with the identification and quantification of proteins and proteoforms present in a biological sample. We enable insights into the complexities and emergent properties of biological systems for drug discovery and development activities. After an initial discussion about your requirements, we will confirm how we can help. If you'd like to proceed, we'll assign an expert team and project manager.
The facility has several main research foci:
• Ultra-sensitive quantification of small-molecule analyses, such as drugs, metabolites and biomolecules
• Comprehensive protein expression profiling and differential proteome analysis
• Ultra-sensitive quantification of proteins/peptides

Technologies
Micro-scaffold Assisted Spatial Proteomics (MASP) - precisely procures spatial information by precise tissue spatial compartmentalization using a 3D-printed micro-scaffold, and accurately/sensitively quantifies thousands of proteins in a whole-tissue slice.
Ion-current-based MS1 global proteomic quantification Ion (IonStar) - an MS1-based quantitative method devised for large-cohort proteomics analysis, which prominently alleviates issues associated with quantitative precision, missing data and false-positive discovery of protein changes.
State-of-the art instrumentation
The Core consists of two instrument rooms, totaling 600 sq ft, housing state-of-the-art liquid chromatography (LC) systems, mass spectrometer (MS) and sample processing instruments:
- Thermo Orbitrap Astral mass spectrometer
