Alliance Pharma’s bioanalytical team provides comprehensive services for both small and large molecules using a variety of platforms from mass spectrometry to ligand binding assays using an assortment of specialized instrumentation. Our analytical laboratories boast thirteen LC-MS/MS systems from three different manufacturers and include various platforms. Nine systems from AB Sciex are each coupled to Shimadzu UHPLC systems, including two API4000 QTRAP systems, two API4000 triple quad systems, three 5500 triple quad systems, and two 6500 triple quad systems. Each system is designed for high sensitivity quantitative analysis of small molecules generated from either in vitro or in vivo studies and in various matrices.
Alliance Pharma’s small molecule mass-spec based bioanalytical team specializes in:
- Development, optimization, and transfer of bioanalytical assays
- Method Validation
- Sample analysis to support clinical (GLP) and non-clinical studies
- Plasma, serum, whole blood, and all tissue types
- Biomarker assay development, validation and sample analysis
- High throughput screening from in vitro ADME assays
- Metabolite identification
The newest additions to the bioanalytical lab include two Agilent 6545 XT Q-ToF high resolution mass spectrometers coupled to Agilent 1290 Infinity II UHPLC systems with PDA and FL detectors. These new systems add additional capacity to our existing high-resolution accurate-mass (HRAM) systems: 1) a Dionex RSLCnano, 2-D nano/micro/cap UHPLC system coupled to a Q Exactive Plus, and 2) an Orbitrap XL from Thermo Scientific. The newest HRAM systems are ideally suited for analysis of proteins and peptides and will allow generation of highly detailed information for intact proteins and antibodies, confirmation of sequence at the peptide level, and sophisticated analysis of both simple and comprehensive post-translational modifications.
The combination of mass accuracy (> 1 ppm) and high resolution (up to 280,000 at m/z 200) allow for increased specificity and sensitivity in extremely complex matrices. The additional capabilities position Alliance Pharma to continue to expand our large molecule qualitative and quantitative analysis capabilities.
