PDS' flagship platform, ProteinMentor, uses Quantum Cascade Laser Infrared (QCL IR) microscopy for high-throughput analysis of Critical Quality Attributes (CQAs) in protein therapeutics. The platform's HT multi-attribute multi-variate (MAM) and label-free analysis provides unprecedented insights into formulation optimization, stability, charge variance, and proteinaceous particle generation propensity, as well as detecting sample contamination by bacteria or other foreign organisms. The platform's patented method provides detailed molecular behavior of the protein therapeutic, enabling high throughput developability assessments in the presence of various excipients under different stressor conditions. Additionally, ProteinMentor is valuable for evaluating batch-to-batch comparability during process-, site- or manufacturing changes, providing statistically robust data to establish analytical biosimilarity.
