Protea Biosciences Group, Inc. announced the release of their advanced Gel Protein Recovery GPR-850 instrument. The GPR® System delivers 
efficient recovery of gel separated intact proteins through a multiplexed, automated, microfluidics chip-based process. The GPR System (consisting of the GPR-850 instrument, GPRchips™, and GPR Buffers and Reagents) enables researchers to recover intact proteins and peptides for subsequent top-down proteomics experiments. This process facilitates effective protein identification, characterization and quantitation by mass spectrometry. The effectiveness of the system is enhanced by the use of proprietary reagents (which utilize Protea’s Progenta™ Surfactants technology) together with the microfluidic-based GPRchip. The GPR System combines these components to provide a high throughput recovery platform for researchers interested in studying intact proteins. The GPR System features several kits specifically designed for specialized down-stream mass spec applications, including ESI-MS and LC-MALDI. The new GPR-850 instrument features an updated user interface, improved mechanical and industrial design, and comes in six different colors to match the personalities of researchers, laboratories, or institutions.
