Transient Gene Expression: paper submissions welcome

NEWS

Transient Gene Expression for Rapid Protein Supply is the topic of an upcoming Special Issue in Processes, an open access journal of chemical and biological process engineering.

Research in this field aims to reduce the cost and time needed to produce proteins of value for academia and industry. In view of this, Dr. Florian Wurm and Dr. Martin Jordan of Merck Biopharma in Switzerland have agreed to be guest editors.

Better media and feeds for high CHO yield

NEWS

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…

SERVICES

From DNA to cell to purified protein product.

We cover the value chain from DNA construction & transfection, to scalable process development for CHO and HEK, to VLP production and rapid protein production for large-scale manufacturing. Our cGMP compliant facility enables the generation of Master Cell Banks (MCB) and Master Working Banks (MWB).

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

Manufacturing in weeks from 1mL to 100L scale.

Process Development

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

VLP Production

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