Gregor Richter has a three decade background in chromatography resins and equipment for the biopharma industry and has supported  numerous projects from early development into large scale process implementation. He was one of the first representatives enabling use of the POROS resin technology in the early 1990s. After holding positions with several chromatography vendors and a CDMO, he joined Thermo Fisher Scientific in 2012 as a technical sales specialist. In 2022, he moved into a global business development role supporting customers with custom resin projects for POROS and CaptureSelect affinity products.

 

## About this event:

#### Date: September 4, 2025

#### Time: 11 am EDT | 8 am PDT | 5 pm CEST

#### Duration: 30 minutes

As biotherapeutics evolve, innovative and complex molecules hold great therapeutic promise but often pose significant challenges in the purification process. Across various modalities (i.e., vaccines, gene therapy vectors, therapeutic proteins, and beyond), standard chromatography purification processes often fall short, leading to inefficiencies and bottlenecks in downstream processes. Attempts to adapt processes utilizing existing resins can be lengthy, costly, and ultimately unsuccessful. A more streamlined approach can be employing a custom chromatography resin tailored to the unique features of the target molecule.

In this webinar, Thermo Fisher will share details from a collaborative custom chromatography resin development program that has streamlined downstream processes to achieve high yield and purity for innovative targets. With over 60 successful programs, this platform leverages advanced affinity ligand and base-bead technology to enhance process efficiency and reduce costs.

 Key takeaways: 

- Analyze case studies where custom resin development solved yield and purity challenges for innovative therapeutic molecules.
- Learn about the collaborative process in developing a custom resin specific to your needs.
