Manufacturer's Response
Thank you for the feedback. We are glad you like the ease of use and data reproducibility, good to hear that the DSC is making an impact in your work in selecting drug candidates.
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.
Key Features:
- Gold standard stability-indicating technique requiring minimal assay development
- Direct and label-free measurement of biomolecular native-state stability in solution
- Standard 96-well plate format for high capacity and easy loading, with thermostatically-controlled storage of up to 6 plates
- Fully integrated autosampler enables unattended analysis of up to 50 samples per day
- Automated cell filling and cell cleaning functions permit unattended operation
- Measurement of very tight binding constants, up to 1020M-1
- Powerful MicroCal PEAQ-DSC software minimizes typical data analysis time and includes:
- PEAQ-Compliance: The system is available with Malvern Panalytical Access Controller (MAC) to limit access to user-defined SOPs and data analysis features. Data can be displayed using the Report Generator with user details and the ability to sign using electronic signatures to facilitate the integration of the workflow into your company’s quality system and aid compliance with 21 CFR Part 11 and Annex 11 regulations. This is provided as an optional accessory
- PEAQ-Performance: Automatically detects and validates system readiness for optimal performance
- PEAQ-Smart (including PEAQ-Finder): For SOP-based operation and data analysis. Provides new algorithms to detect even subtle peaks and shoulders, facilitating the automatic, non-subjective identification of multiple transitions, such as those seen in multi-domain proteins
- PEAQ-Compare: For the quantitative comparison of DSC traces for comparability studies, ideal for batch-to-batch and biosimilarity studies
- Network-ready: email updates sent during the analysis to keep you informed of assay progress
Differential scanning calorimetry: Your guide to analyzing proteins for vaccine stability
In this application note, Malvern Panalytical describes how differential scanning calorimetry (DSC) can help to optimize your process and speed up the selection of vaccine candidates.
Biomolecular stability analysis for the regulated environment
Differential Scanning Calorimetry (DSC) is a powerful analytical technique which characterizes the thermal stability of proteins and other biomolecules. In solution, these molecules often undergo thermally-induced conformational changes, such as the breaking of non-covalent bonds leading to the unfolding of a protein. The information delivered by DSC is ‘gold standard’, label-free stability data which can be used for a variety of purposes.
Biophysical Application of Calorimetric Methods to Protein Misfolding And Aggregation Examinations
Unfolded proteins fold into thermodynamically-favorable native structures under the correct physiological conditions for gain of function. This whitepaper describes how differential scanning calorimetry and isothermal titration calorimetry can be used as a powerful method for the thermodynamic investigation of interactions between diverse biomolecules and inorganic compounds. It details some examples from literature of the methods application in studying amyloid fibrillation.
The New MicroCal PEAQ-DSC Automated System
Differential scanning calorimetry (DSC) is an established biophysical tool for protein stability characterization during biopharmaceutical drug development. The MicroCal VP-Capillary DSC system is an automated DSC system that performs TM screening and evaluates protein stability for a wide range of biopharmaceutical applications. This white paper discusses the new and improved features of the MicroCal VP-Capillary DSC system, including PEAQ-Compliance, PEAQ-Smart, PEAQ-Finder, PEAQ-Performance and PEAQ-Compare, which make DSC even easier to use, and produce reliable, reproducible DSC data.
