Tm Bioscience Corporation To Supply St. Joseph’s Hospital And Medical Center With Tag-It(TM) Reagents

TORONTO, Feb. 13 /PRNewswire-FirstCall/ - Tm Bioscience Corporation , a leader in the commercial genetic testing market, today announced it has signed an agreement to supply St. Joseph’s Hospital and Medical Center (Phoenix, Arizona) with Tag-It(TM) reagents for use in its Cystic Fibrosis (CF) gene assay.

“We selected Tm’s Tag-It(TM) platform because we were impressed by its performance and flexibility. Tm’s technology has allowed us to develop an assay testing for numerous CF associated mutations at once in a single well, an extremely time-efficient and cost-effective solution,” said John Stone, Director of Laboratory Services at St. Joseph’s Hospital. “Because the platform is open and flexible, we ultimately anticipate providing our patients with a broader menu of important genetic tests using Tm reagents.”

Located in the heart of Phoenix, Arizona, St. Joseph’s Hospital and Medical Center is a 536-bed, not-for-profit hospital that provides a wide range of health, social and support services, with special advocacy for the poor and underserved. Founded in 1895 by the Sisters of Mercy, St. Joseph’s was the first hospital in the Phoenix area. The hospital is part of Catholic Healthcare West (CHW), one of the largest healthcare systems in the West with 40 hospitals in Arizona, California and Nevada.

“We look forward to working with St. Joseph’s Hospital to provide leading edge medical laboratory services for the state of Arizona,” said Greg Hines, President and CEO of Tm Bioscience.
