Sigma® Life Sciences Presents a Technical Webinar – High Protein Yields in Shaken Cultures by EnPresso® Growth System

Webinar Title: High Protein Yields in Shaken Cultures by EnPresso® Growth System


EnPresso, a proprietary growth system from BioSilta Ltd, applies slow enzymatic glucose release to control the growth and protein synthesis rate in bacteria and yeasts. This high-cell-density growth system can be used in any shaken cultivation device at various scales. In this webinar, Dr. Kaisa Ukkonen and Dr. Antti Vasala will review the basic requirements for successful high-cell-density cultivations and discuss common reasons for failures in E. coli-based protein production, the focus being on the cultivation conditions. In particular, prerequisites for successful scale-up will be presented. The webinar also features examples on the use of EnPresso demonstrating the time and cost savings enabled by this powerful growth system, and presents an interesting alternative protein expression protocol: IPTG-based autoinduction.

 What Will You Learn?

  • Review of the obstacles in protein production (reasons for poor productivity)
  • Insight into the enzymatic glucose release system
  • How to maintain or improve the productivity at scale-up
  • Recent applications of EnPresso® B Growth Systems

 Who Should Attend?

Researchers who need to express functional protein in bacterial shaker culture systems.
