Description
The IHC-ROS1-SP384 test refers to an immunohistochemistry (IHC) assay used to detect the presence of ROS1 protein in tissue samples, particularly in lung cancer. The “SP384” designates the specific antibody clone used, which is the VENTANA ROS1 (SP384) Rabbit Monoclonal Primary Antibody. This test is primarily used as a screening tool to identify potential ROS1 fusion-positive cases, which can then be further investigated with other methods like FISH.
