Confirmation of S100P(+)/SV40-T(+) cells and HGD(+)/SV40-T(+) cells in urine cell block by double-immunostaining (×1,000). Double-immunostaining with anti-SV40-T antibody and anti-S100P antibody showed a cell with red cytoplasm (S100P) and brown nuclei (SV40-T) (A, arrow) and a cell contained two nucleus (A, asterisk). Double-immunostaining (×1,000) with anti-SV40-T antibody and anti-HGD antibody showed a cell with red cytoplasm (HGD) and brown nuclei (SV40-T) (B, arrow).
