Roche launched the Ventana ROS1 rabbit monoclonal primary antibody, which the company said is the first and only in vitro diagnostic ROS1 immunhistochemistry assay. The test detects the presence of ROS1 protein in tisuue and may be used to identify ROS1-positive cancer in patients. College of American Pathologists and National Comprehensive Cancer Network guideliness recommend ROS1 testing for confirmed lung adenomcarcinoma cases, Roche noted. The test is a US class I/CE IVD device and can be used with Roche's BenchMark series of automated staining instruments.
