Billerica, MA, August 23, 2011 – Seahorse Bioscience, the leader in cellular bioenergetics instrumentation and kits has been listed in the top 25% of the 2011 Inc. 500|5000 list of the fastest-growing, private companies in America, and is ranked 34th among the top 50 businesses in Massachusetts.

Inclusion in Inc. Magazine's annual Inc. 500|5000 list is considered to be one of the most prestigious awards for high-growth companies in the private sector, recognizing the most dynamic, growing, entrepreneurial companies that are changing the business landscape. Companies are ranked according to their growth in revenue from 2004 to 2010.

"In the five years since we launched our first product, Seahorse has changed the way that scientists study 'bioenergetic' defects in living cells. Scientific publications containing Seahorse data, nearly two per week so far this year, highlight new discoveries in age-related diseases, including cancer, diabetes, Alzheimer's, Parkinson's, Huntington's and cardiovascular disease," said Jay Teich, Seahorse Bioscience, CEO and Founder."

"Now, more than ever, we depend on Inc. 500|5000 companies to spur innovation, provide jobs, and drive the economy forward. Growth companies, not large corporations, are where the action is," stated Jane Berentson, Inc. Magazine, editor-in-chief.

The Seahorse XF Extracellular Flux Analyzer measures cellular bioenergetics, simultaneously measuring the two major energy-producing pathways of the cell - mitochondrial respiration and glycolysis - in a microplate, in real-time. The XF Analyzer and Stress Test kits are standardizing the measures of mitochondrial (dys)function and glycolysis, enabling scientists to better understand the connection of physiological traits of cells with genomic and proteomic data. This knowledge will generate new insights into mitochondrial (dys)function, which will lead to a greater understanding, and new treatments of diseases as the human lifespan increases.
