BILLERICA, Mass., April 1, 2013 /PRNewswire/ --Seahorse Bioscience, the world leader in instruments and assay kits for measuring cell metabolism recently launched the XF Plasma Membrane Permeabilizer (PMP), a reagent that enables scientists to measure the biochemistry and mechanisms of mitochondrial dysfunction, without the need for mitochondrial isolation or detergent-based permeabilization methods.

XF PMP was developed in partnership with the Pioneer Valley Life Sciences Institute (PVLSI), a joint venture of Baystate Medical Center and the University of Massachusetts Amherst, with the dual missions of biomedical research and economic development. The technology was exclusively licensed to Seahorse Bioscience by UMass Amherst and Baystate Health, the parent organization of Baystate Medical Center.

XF PMP can be used with the Seahorse XFe Extracellular Flux Analyzer, an instrument for measuring cell metabolism, in real-time, in a microplate. The reagent was developed for XF technology in part by Dr. Nagendra Yadava, the John Adams Investigator at PVLSI; and Dr. Alejandro Heuck, Ph.D., an Assistant Professor of Biochemistry and Molecular Biology at UMass Amherst.

"In the development of this potent new tool in biomedical analysis, we see the tremendous potential of collaborations between clinical and academic researchers and ingenuitive companies like Seahorse," said Richard Friedberg, M.D., Ph.D., chair of Pathology and chair of the Intellectual Property Committee at Baystate Health, who represented Baystate in working with Seahorse and UMass to establish the licensing agreement.

XF PMP creates pores in the cell plasma membrane, and delivers a degree of precision and ease-of-use that has not been available to scientists researching cell metabolism. A key element of XF PMP is the ability to assess mitochondrial function in adherent monolayers of permeabilized cells without damaging the mitochondrial membrane. By doing so, XF PMP enables metabolic substrates, compounds, and small proteins that otherwise would not cross the plasma membrane to reach the mitochondria.

"Seahorse's new XF Plasma Membrane Permeabilizer [PMP] enabled us to demonstrate that clinically-relevant concentrations of thiazolidinediones, a class of insulin sensitizers that includes Actos, specifically inhibited the mitochondrial pyruvate carrier, a protein at the hub of cellular metabolism. The simplicity and reliability of XF PMP made it easy to interrogate the mitochondrial function of small clinical samples and genetically modified cells without mitochondrial isolation, experiments that are traditionally difficult or impossible. Our work is providing a new understanding of the mechanism of action of an important class of drugs, and opens a new avenue for the development of drugs to treat diseases including type 2 diabetes, neurodegenerative disease, and heart failure," stated Anne N. Murphy, Ph.D., Associate Professor of Pharmacology at University of California, San Diego.
