Differential scanning microcalorimeter MicroCal PEAQ-DSC

DSCfor biomolecular stability analysis

The MicroCal PEAQ-DSC system provides highly sensitive, easy-to-use microcalorimetry that helps reduce the time and cost associated with stability testing and comparability analysis. The MicroCal PEAQ-DSC is a manual instrument with a cleaning device, which can be upgraded to an automated version upon request. Data generated by the MicroCal PEAQ-DSC provides critical guidance for biopharmaceutical development in protein engineering, (pre)formulation development, process development, manufacturing change control and biosimilarity and biocomparability studies. 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.
