Precision in production: optimizing monitoring and quality control for high-value plasmids

Plasmids are vital for producing viral vector-, mRNA-, and DNA-based therapies and vaccines. However, current development efficiencies and production capacities are insufficient to meet the growing demand. Join us as we delve into strategies to enhance the efficiency and control of plasmid production.

Quality control (QC) is paramount throughout the production process to ensure the safety, purity, and potency of the final product. Spectrophotometric analysis, particularly the 260/280 UV absorbance ratio, is commonly used to assess plasmid purity. However, traditional methods have limitations such as fixed-pathlength, which is one of essential characteristics of conventional spectrophotometers. This can introduce unnecessary risks and errors due to sample preparation and dilution requirements.

Attend this webinar for insights into the capabilities of Variable Pathlength Technology (VPT), its benefits compared to traditional UV-visible techniques and sensor equipment, and how this innovative technology enables rapid and precise real-time concentration measurement across a broad range of concentrations.

  • Discover strategies for optimizing E. coli cell growth performance through the implementation of in-line, real-time OD600 (abs/mm) monitoring during the fermentation process
  • Review case studies of VPT platform implementation and validation for downstream QC/at-line pDNA purity analysis
  • Discover how the CTech™ SoloVPE® (at-line) and the FlowVPX® (in-line) Systems serve as essential Process Analytical Tools (PAT) for optimizing and controlling the plasmid development and production process
  • Get introduced to PAT-driven in-line VPT integration for automated process control (this may or may not be RPM) and explore how other users have integrated the FlowVPX into their existing downstream UF/DF processes
