We collaborated with ProteoGenix for the development of monoclonal antibodies targeting a cell protein. The specificity, functionality and strong affinity of the antibodies developed convinced us to move forward with further humanization and bispecific development.

We appreciated the strong technical and scientific support of our contact which was decisive for the success of our project.

The word of our CEO

As a cofounder of ProteoGenix, I feel extremely proud and privileged to lead a team of spectacularly devoted and talented scientists committed in implementing our strong company values. Our contribution to the fascinating biopharma industry increases the proportion of monoclonal antibodies of any kind of format reaching the market and consequently improves human health.

The engineering of monoclonal antibodies into high potency IgGs, bi-specific antibodies, ScFvs or antibody-drug-conjugates (ADC) or any other format is an exciting task that we perform with passion every day. Our deep involvement in moving all biomolecules forward to the clinic in the best way reflects today’s incredible associated societal expectations. On behalf of ProteoGenix team, I look forward to serving you with sincere pleasure, carrying out your monoclonal antibody productions and pushing your leads to the clinic and eventually to the market.
