Prometheus Panta


Whether you’re working in biologics formulation optimization, developability, or comparability assessments, count on Prometheus Panta to provide multi-parameter stability characterization and trustworthy results for your candidate molecules.

Collect data on thermal unfolding, particle sizing, and aggregation simultaneously, throughout the entire thermal ramp, for high-resolution, domain-specific stability characterization of biologics.

Prometheus Panta provides the highest quality data on multiple biophysical attributes of your biologics candidates. See unprecedented detail that unveils subtle differences between candidates, so you eliminate less stable options earlier in the pipeline.

The equipment is accessible to both internal and external users upon prior request. Individuals interested in utilizing the equipment should contact the device administrator. Only trained operators can schedule the use of the equipment, or alternatively, the measurement can be conducted by the experienced staff of the Department of Molecular Biology and Nanobiotechnology.
