ExcellGene at Bioprocessing Summit Europe

EVENT 20-22 MARCH 2018

Prof. F. Wurm will provide a keynote lecture: CHO: Optimizing Cell Culture Technologies for Manufacturing of Recombinant Proteins – Past, Presence and Future at the Bioprocessing Summit Europe conference in Lisbon on March 20th.

Dr. Maria Wurm, CEO of ExcellGene will provide a seminar on Bioreactor-Based Optimization and Scale-up Issues for Large Scale Manufacture with Suspension Cultures of Animal Cells, on March 22.

Better media and feeds for high CHO yield


In an article written in November 2017 by Dr. Angelo DePalma in Genetic Engineering and Biotechnology News (GEN), ExcellGene and Prof. F. Wurm were referred to discussing the benefits of better media and feeds as the main driver for the higher yields from CHO cells and the processes developed for large scale manufacturing. This conclusion is based on more than 3 decades of observation and analysis of CHO cells for manufacturing purposes…


Everything from DNA vector to purified product and process for large-scale manufacturing.

We cover the value chain from DNA construction & transfection, to scalable process development, to rapid protein manufacture or VLP production and the development of scalable (GMP) processes.

ExcellGene™ technologies are the most advanced for rapid production of recombinant proteins or virus vectors – transient or stable.

Cell-line Development

From DNA to high-yielding clonal population – ready for cGMP banking

Rapid Protein Production

Production in weeks from 1mL to 100L scale.

Process Development for High Yield

Fine-tuning of media and process conditions, parameters for virus or protein.

VLP Production

HEK cell-based production 1ml to 10L,
baculo virus-free.

cGMP Master Cell Banking

300-500 vials


Science-driven, on every level.
