Figure 2. A-F demonstrates immunohistochemical (IHC) staining for BRM in Rhabdoid tumors and in a positive control lung cancer as well as staining for BAF47 in Rhabdoid tumors.
A is the positive control that shows BRM immunoreactivity in a non-small cell lung tumor. B and C demonstrate low to moderate BRM staining, respectively. D illustrates the lack of BRM staining in Rhabdoid tumors, where the black arrows indicate internal positive controls. E illustrates positive BAF47 staining in a non-small cell lung tumor (positive control), whereas F illustrates the absence of BAF47 expression in Rhabdoid tumors by IHC.
