Innovative DNA and Protein Products

Protein Potential's Research and Development Group focuses on producing intellectual property and recombinant bacteria, recombinant protein, and DNA products. Protein Potential's primary focus is on development of vaccines to protect against enteric diseases including shigellosis, diarrhea caused by ETEC, and typhoid fever and bioterrorism agents using its platform technology of recombinant, acid-stabilized Ty21a. Protein Potential is also developing subunit vaccines for Plasmodium falciparum and Plasmodium vivax malaria.

Protein Potential's Products and Services Group provides pharmaceutical and biotechnology companies, and government and academic institutions with high quality, purified, recombinant proteins and DNA plasmids for research and development. Protein Potential also provides process development, documentation, and technological know-how to transition therapeutic, vaccine, and diagnostic proteins and DNA plasmids to large-scale cGMP manufacturing.
