Production in mammalian cells

Our team offers guidance and tailored services to define the most relevant strategy for an efficient expression of your protein and antibody in mammalian cells.
Commercial manufacturing of small batches for nanodrugs

Custom protein and antibody production in mammalian cells

GTP Bioways offers expert services for the production of proteins and monoclonal antibodies in mammalian cells.

Our services are designed to provide milligrams to grams of your antibodies and proteins in short turnaround times.

We can conduct up to hundreds of transfections in parallel, to provide materials for your mAb screening campaigns.

Expertise and flexibility to boost your programme

Over the past 20+ years, our team has expressed thousands of antibodies, antibody fragments and bispecific antibodies, and a variety of proteins including cytokines, fusion proteins and receptors.

Advanced Biodesign

Efficient transient protein expression in CHO & HEK cells

To deliver your proteins in short turnaround times, our expert scientists have developed an efficient transient transfection platform in CHO or HEK cells.

Thanks to our optimised expression conditions, we routinely achieve high expression yields for a variety of proteins and antibodies.

Development of stable CHO pools and clones

In addition to offering production by transient transfection, we can develop stable CHO pools and clones in order to meet your needs for regular and/or large-scale supply of your antibody or protein.

With our unique tailored approach for cell line development, we can develop in short timelines a cell line adapted to your needs.

Our technology enables to reach high productivities and our process guarantees a full traceability to allow further transfer of the cell line to GMP manufacturing.
