Immunostaining for Baf47 nuclear antigen. As expected no nuclear positivity is present in samples of a Rhabdoid Tumor of the kidney. Only endothelial nuclei are positive in all samples. Positive infiltrating lymphocytes are present and highlighted in the RCL2 sample. Other tumor samples such as Neuroblastoma (PAGA and RCL2, second row) Wilm's tumor (Z7) and ductal carcinoma (Formalin) as well as normal testis (FineFixx) show uniform nuclear positivity.
