Custom monoclonal
in vitro production

in vitro Production

At Eurogentec, monoclonal antibodies are produced exclusively in vitro, in accordance with the Belgian animal regulations and the 2010-63-EU directive for animal welfare.

Up to 100g mAb

Our facilities are equipped to produce from mg to 100g mAb.

For requests of 200mg and more, a test study is systematically performed to evaluate the clone productivity.

The Best production scheme

Based on the requested mAb amount and the clone productivity, we select the best production scheme using flasks, roller bottles or bioreactors.

Mycoplasma diagnostics and cell line decontamination can also be performed.

Production scales



Starting materials

The Hybridoma cells can be developed at Eurogentec or provided by the customer.

Boost my hybridoma’s

Our antibody experts have established a proprietary protocol to boost the productivity of hybridomas. It usually gives a productivity increase from +20 to +600% (recorded so far).
