ALAMEDA, Calif. and BARCELONA, Spain, May 31, 2016

"Singulex is pleased that Grifols has made this significant investment in Singulex and our SMC technology platform," said Guido Baechler, president and chief executive officer, Singulex. "Our technology already has the power to provide definitive answers for physicians and patients for improved health outcomes and is backed by extensive peer-reviewed publication and industry adoption. This new partnership will help us shape and develop the future of blood screening technology and make major advancements in the safety of next generation blood products."

Single molecule counting technology, developed by Singulex for clinical diagnostic and scientific discovery, has the power to identify biomarkers of diseases that were previously undetectable. Applying this technology to blood screenings will allow for greater diagnostic sensitivity, accuracy and efficiency to ensure the safe capture and processing of blood and plasma products.

"As one of the world's leaders in the manufacturing of plasma products to treat a variety of rare, chronic and life-threatening conditions, safety and screening of donated human blood and plasma is critical for Grifols," said Carsten Schroeder, President of the Grifols Diagnostic Division. "Singulex' SMC technology and leadership in next generation immunodiagnostics presents Grifols with the diagnostic sensitivity, accuracy and reliability to develop more advanced blood screening platforms."

Singulex has developed the Sgx Clarity™ System, a fully-automated in vitro diagnostics system that will soon bring the proven SMC technology to hospital and reference laboratories worldwide. Singulex also provides clinical laboratory testing services which enhance early detection of cardiac and vascular disorders.
