The MicroCal PEAQ-DSC Automated system delivers high throughput, highly sensitive protein stability analysis with low sample consumption, in an automated, integrated platform for increased productivity.  All cell filling and cleaning functions are fully automated for walk-away operation. 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.
