Protea and Proteos Announce Co-Marketing Agreement

5/5/17

Protea Biosciences Group, Inc. (OTCQB: PRGB) and Proteos, Inc. announced today that they have entered into a joint co-marketing agreement. This mutual partnership allows Protea to combine Proteos' protein production capabilities alongside Protea's proprietary bioanalytical services, and allows Proteos to market and promote Protea's proprietary bioanalytical services with their custom protein production services.

"We are excited to utilize our protein characterization capabilities and workflows on the high-quality proteins and antibodies that are expressed and purified by Proteos," stated Haddon Goodman, Vice President, Corporate Development. He added, "Providing detailed analysis of protein structure, sequence and post-translational modifications is key to understanding important information about the proteins being produced. This co-marketing agreement aligns with our strategy of bundling our bioanalytical capabilities with leaders in related life science and technology fields."

Recent advancements in recombinant protein production technologies, combined with an ever-increasing understanding of biology, are discovering novel proteins at a rapid pace. These novel proteins are useful in a wide variety of biotherapeutic, industrial and diagnostic applications. With these advances comes the need for seamlessly integrating quantitative analysis of these proteins. The combined availability of the Protea and Proteos technology platforms will benefit companies and research institutions by streamlining their project development cycles. Both companies plan to actively co-market their respective capabilities to the biopharmaceutical, biotechnology, life science and academic sectors.

"It's an absolute pleasure to be working with Protea and being able to offer comprehensive protein analysis capabilities alongside Proteos' own protein production and purification platforms," stated Dr. Al Darzins, President. "This partnership is likely to have significant market impact by providing our clients with a one-stop shop for the high-quality production, purification and analysis of proteins so critical for performing cutting edge biochemical research."
