Aggregation and Stability Analysis

ARGEN, by Fluence Analytics, adds another powerful tool to the protein scientist’s arsenal. It is a light scattering instrument that measures the pharmaceutical stability of therapeutic proteins and peptides and the quality of natural and synthetic polymers. The instrument is composed of 16 independent cuvette sample cells capable of precise control of thermal and mechanical stress. By continuously monitoring the state of its samples, the lab instrument provides continuous, kinetic data yielding early detection of aggregation, degradation and particle formation under independently controlled stressor conditions.
