The product types manufactured with microbial expression systems at Richter-Helm BioLogics include recombinant proteins and peptides, plasmid DNA, and bacterial vaccines.

Recombinant proteins account for the largest share. But Richter-Helm BioLogics has also accumulated extensive experience with many other proteins such as cytokines, fragment antibodies, new antibody-like molecules, and hormones.

Encouraging therapeutic successes have recently been reported for various gene therapies. Plasmid DNA is an important molecule in this field, whether it is used directly as a therapeutic vaccine or indirectly as a critical raw material for producing genetically modified viruses. Richter-Helm BioLogics has been producing and analytically testing plasmid DNA for nearly 20 years.


The bacterial vaccines produced at Richter-Helm BioLogics include living, attenuated, and inactivated whole-cell vaccines, cell fragments, and surface polymers.

Richter-Helm BioLogics also leverages considerable experience with and flexibility for complex biopharmaceuticals.

All kinds of microbial-derived biopharmaceuticals can be produced at Richter-Helm BioLogics. Recombinant protein projects account for the bulk of the manufacturing services we provide.
