Protea Announces Commercial Release of REDIchip™

New Chip Technology Provides Rapid and Sensitive Quantitation of Small Molecules

ST. LOUIS, MO--(Marketwired - June 01, 2015) - Protea Biosciences Group, Inc. (OTCQB: PRGB) ("Protea") announced today that it is launching a new chip-based technology at the 63rd American Society of Mass Spectrometry (ASMS) Conference on Mass Spectrometry and Allied Topics, held in St. Louis, MO. The nanopost array technology, called REDIchip™ (Resonance-Enhanced Desorption Ionization), was invented in the laboratory of Akos Vertes, PhD., Department of Chemistry, The George Washington University, and exclusively licensed to Protea.

"This week we are launching the REDIchip as a solution for researchers who desire to detect and quantify small molecules without the need of an interfering matrix using existing MALDI platforms. At ASMS, we have the opportunity to present several of the many applications of this new silicon chip, all made possible by the structured nanopost array design," stated Haddon Goodman, Imaging Program Manager at Protea. He continued, "The REDIchip manufacturing process uses established robust and reproducible methods of silicon chip production, enabling reliable and reproducible, matrix-free small molecule quantitation."

Several applications of Protea's REDIchip target plate are being presented at this week's ASMS conference, and the product is now available for commercial use. Select applications highlighting REDIchip workflows are being presented, including the metabolic profiling of biofluids (Tuesday, Poster 189), rapid quantitation of pharmaceutical drugs (Wednesday, Poster 159), and the quantitation of alkaloids in plant homogenates (Monday, Poster 246).

REDIchips are compatible with a variety of MALDI systems, and enable rapid and reproducible sample analysis of small molecules by laser desorption ionization.
