Protea at 2013 Needham Healthcare Conference

Morgantown, West Virginia, UNITED STATES

MORGANTOWN, W.Va., April 24, 2013 (GLOBE NEWSWIRE) -- Protea Biosciences Group, Inc. ("Protea"), a leading bioanalytics company, announced today that Steve Turner, Protea's CEO, will present at the Needham & Company 12th Annual Healthcare Conference on April 30th, 12:50 PM ET, at the Westin Grand Central Hotel in New York City. Mr. Turner will present the Company's marketing of its groundbreaking LAESI technology platform, that enables researchers to generate comprehensive mass spectrometry imaging datasets on their tissue, cell or biofluid samples, for use in drug and biomarker discovery, without sample preparation.

"We are pleased to be invited to present at the prestigious Needham Healthcare Conference," stated Steve Turner, CEO. He added, "With our proprietary LAESI technology platform we can give our customers a whole new dimension in biomolecular analysis, mapping their compounds, such as drugs and metabolites, as they appear in tissues, even living cells and bacterial colonies."

LAESI technology was invented in the laboratory of Akos Vertes, PhD., Professor of Chemistry, George Washington University, and brought to market by Protea. LAESI (Laser Ablation Electrospray Ionization) technology allows two and three dimensional distribution profiling of biomolecules in biological samples for unambiguous drug / target interaction studies, as well as the study of bio-dynamics directly in living cells. Using LAESI mass spectrometry, multiple biomolecules can be mapped in a single analysis, providing comprehensive information on the different dynamics and biological processes underway in a cell sample.

The company recently completed the installation of LAESI instrumentation at the Waters Corp (NYSE:WAT) Waters MS Technology Centre located in Manchester, England, where researchers visiting the Waters Customer Center can experience first hand the LAESI DP-1000 instrument platform.

A replay of the presentation will be available at: on April 30.
