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.

ProteoGenix, a leading antibody
production company

ProteoGenix is a leading antibody production company founded in 2003. Our integrated solutions from gene to biotherapeutics& diagnostics make us the preferred partner of pharmaceutical & biotech companies for their custom assay development and therapeutic antibody discovery :

– Antibody generation including antigen design: hybridoma technology or phage display
– Antibody engineering: humanization, affinity maturation, reformatting (bispecific antibodies, ADC…), subtype or isotype switching…

– Antibody production: recombinant monoclonal antibody production, stable cell line development…
– Protein production: E. coli, B. subtilis, yeast, insect cells, mammalian cells
– Custom peptide synthesis
– Custom gene synthesis

Let’s partner and push your biotherapeutics to the clinic!
