Protea Biosciences and InSphero AG Enter into Collaboration and Co-marketing Agreement to Combine 3D Technologies

Schlieren, Switzerland, and Morgantown, West Virginia, July 9, 2014 – Protea to apply direct 3D molecular imaging platform to InSphero's 3D InSightTM Microtissues. 

Protea Biosciences Group, Inc. (OTCQB:PRGB) and InSphero AG jointly announced today that they have entered into a collaboration that will combine each company’s respective 3D technology. InSphero AG is the leading supplier of 3D organotypic microtissues for in vitro toxicology and efficacy studies, with models derived from liver, pancreas, tumor, and brain tissue that yield a high level of predictability during drug development compared to traditional 2-dimensional cell culture and other in vitro model systems. The collaboration will use Protea’s proprietary LAESI® direct molecular imaging platform to analyze InSphero’s proprietary 3D InSight™ microtissues, creating 3D molecular profiles for tissue characterization, drug metabolism and distribution, pharmacokinetic and toxicity applications. From this collaboration, Protea and InSphero expect to create new products and services that may be marketed to pharmaceutical and biotechnology researchers worldwide.

“The understanding of disease and the development of new pharmaceuticals continues to be an enormous challenge, one that requires new technologies”, stated Protea’s CEO Stephen Turner. He added, “We believe that InSphero’s 3D microtissues deliver a new level of insight and predictability to the drug development process. We are honored to be working with InSphero’s team of scientists and to have the opportunity to apply our LAESI direct molecular imaging technology to the analysis of their 3D microtissues.”

InSphero CEO and co-founder Dr. Jan Lichtenberg believes the partnering of the two 3D technologies is a natural fit. “The LAESI technology increases the power of mass spectrometry, and is uniquely suited to meet the needs of researchers using our 3D microtissues. The ability to reconstruct the molecular profile of a tissue in three dimensions, including endogenous proteins, drugs, and compound metabolites, will facilitate a deeper characterization of 3D cell models, and open doors to novel applications that can further enhance their utility in drug discovery and development.”
