The presentation was featured in the oncology session of the InSphero user group meeting and is the first publicly released data from the collaboration between Protea and InSphero. The presentation highlights Protea's protein and lipid mass spectrometry imaging data of InSphero's 3D microtissues and includes data from supporting modalities such as protein and lipid profiling via mass spectrometry and bioinformatics pathway analysis. Dr. Seeley will be presenting additional data from the collaboration at the November 20, 2014 InSphero user group meeting that is being held in Boston, Massachusetts.

"The data presented by Dr. Seeley is very exciting as it highlights the capabilities of Protea's scientific team and the multiple technological capabilities we have assembled, which we feel complement one another," stated Steve O'Loughlin, Protea's Vice President, Corporate Finance and Development. "We are pleased with the progress we have made with InSphero through this collaboration and look forward to presenting additional data at the next user group meeting in Boston while continuing to progress towards commercial opportunities through the combination of our respective technologies."

Dr. Randy Strube, Director of Global Marketing for InSphero, was excited to see the data generated from 3D tumor microtissues, stating "It not only meant initial protocols for processing 3D microtissues were successfully established, but were also capable of identifying many molecules we would expect to see in tumor tissues. I think attendees at the user group meeting got a feel for the combined power of the two technologies, and the types of questions they can help answer."
