Cell Services

Our highly skilled scientific experts provide a one-stop-shop from cloning to development of stable cell lines or GMP-compliant Research Cell Banks (RCB). Both cell line services rely on powerful and well-established platforms: our proprietary ExoIN technology (stable cell line generation) and CHOvolution™ platform (GMP-compliant production cell line). Our clients and partners from the pharmaceutical and biotechnology industry rely on our highly-customized cell line services and benefit from our longstanding expertise and in-depth know-how on stable expression of recombinant protein in different cell lines. To optimally support our clients’ needs, we always work in close collaboration with our clients to ensure transparency, high quality and maximum success.

Cell Services FAQs

What quality control is carried out with the produced cell lines?

For all cell lines generated at trenzyme, a standard final quality check is carried out. This comprises thaw-viability assay and mycoplasma test. Additional analysis and an extended quality check including stability check are available.

I would like to order the generation of an assay cell line. How long does it take?

The timeline for the generation of a basic pool starts at 5 weeks and for clonal cell lines at 13 weeks.

What kind of analysis of the target expression do you offer?

Depending on the target and your specific requirements we can test the stable cell line for GOI expression by a variety of methods. You can choose from qPCR, Western blot, FACS analysis, ELISA, IF or cell-based assays.
