TechTalk: Overcoming barriers in expressing challenging proteins with advanced expression systems
Friday, July 31 at 16:30 BST | 17:30 CEST | 11:30 EDT | 08:30 PDT
Join this TechTalk to discover practical strategies for improving the expression of next-generation biologics that can be difficult to produce using conventional transient expression systems. Learn how advanced mammalian expression technologies can support recombinant protein production, from gene synthesis and optimization through expression, purification, and characterization.
The session will highlight how the new Thermo Fisher Scientific Expi293™ PRO and ExpiCHO™ K1 PRO Expression Systems can help improve yields for monoclonal antibodies, bispecific and multispecific antibodies, and other challenging recombinant proteins. Attendees will also explore how integrated workflows and early developability assessment can help reduce development risk and accelerate therapeutic candidate progression.
This TechTalk will be presented by Thermo Fisher Scientific experts, who will share practical insight into overcoming low protein expression, streamlining biologics development workflows, and improving the efficiency of therapeutic protein production.
