The discovery of Polymerase Chain Reaction (PCR) technique, by Kary B. Mullis, allowed scientists to generate millions of copies of DNA. In 1991, Roche bought the rights to PCR from Cetus and invested in refining the science for use in molecular diagnostics to detect diseases. Launching the first FDA-approved PCR test in 1993, Roche Molecular Diagnostics has not only defined and refined PCR, but it has remained the clear leader of this technology.
