Malvern Panalytical - MicroCal PEAQ-DSC Automated
The MicroCal PEAQ-DSC Automated system delivers high throughput, highly sensitive protein stability analysis with low sample consumption.
Data generated by the MicroCal PEAQ-DSC Automated provide critical guidance for biopharmaceutical development in protein engineering, (pre)formulation development, process development, manufacturing change control and biosimilarity and biocomparability studies. Unattended operation enables 24-hour screening, while the integrated software streamlines workflows, facilitates non-subjective data analysis, performance qualification and compliance with 21 CFR Part 11 and Annex 11 regulations, all delivering high integrity data and driving productivity in biopharmaceutical research.
Differential Scanning Calorimetry (DSC) is a powerful analytical tool for characterizing the thermal stability of proteins and other biomolecules. The technique measures the enthalpy (ΔH) and temperature (Tm) of thermally-induced structural transitions of molecules in solution. This information provides valuable insights into factors that stabilize or destabilize proteins, nucleic acids, micellar complexes and other macromolecular systems. The data are used to predict shelf-life of biomolecular products including biopharmaceuticals to enable batch-to-batch and biosimilar versus innovator molecule comparisons, to develop purification strategies, to characterize and evaluate protein constructs, and to rank the affinities of ligands to their protein targets in small molecule drug discovery programs.
The high-throughput, high-sensitivity MicroCal PEAQ-DSC Automated system features software that streamlines workflows through simplified experimental setup and flexible instrument scheduling. Automated data analysis supports the generation of high integrity thermal stability data and delivers compliance with regulatory requirements, whilst allowing easy integration into existing data handling and transfer systems.
