Services Offered

Viropro offers cell line development services using various expression vector technologies (constitutive/inducible) designed for biopharmaceutical manufacturing. Industrially adapted CHO (CHO-S and DG 44) and HEK-293 cell lines can be provided for development. 

Rather than investing in dhfr or un-optimized standard constitutive CMV expression vector technologies that are often pre-destined to increase development time, costs and impose a ceiling on maximal expression levels obtained, your project can certainly benefit from the technologies and know-how that Viropro has to offer your organization.

The expression vectors Viropro uses are particularly well suited for the production of MAbs as shown in the poster by Viropro and Invitrogen presented at the European Society for Animal Cell Technology (ESACT) 2009 conference in Dublin, Ireland. This serves as an example of Viropro’s cell line development expertise.  Our co-published data demonstrates our ability to select for an industrially interesting MAb producing cell line with yields of 2 grams/liter in a standard fed-batch process.

Choosing a production clone that is sufficiently stable for scalability to manufacturing scale is crucial in process development. Through access to some of the most advanced Flow cytometry technology available, as well as standard expression stability analysis, Viropro can provide a partner with a detailed picture of expression stability of a clients cell lines.
