Precision Therapeutics, Inc. and Med BioGene Inc. announced that Precision Therapeutics has successfully completed their previously announced clinical studies to validate the use of LungExpress Dx with tissue preserved by RNAlater, a molecular fixative. RNAlater eliminates the need to flash-freeze specimens and to keep specimens frozen throughout storage and transport, a process that can be cumbersome and costly. It also eliminates the need for preserving tissue in formalin, which is known to cross-link and degrade the nucleic acids rendering them less suitable for specific downstream molecular applications.

The clinical studies were conducted using patient specimens prospectively accrued by Precision from a consortium of medical centers in the United States. Precision expects to commence commercialization of LungExpress Dx in its CLIA-certified laboratory by mid-2013. In advance of commercialization, Precision has established an advisory board comprised of world leaders in lung cancer research and treatment from the United States, Canada, France and Italy.
