antibody in fresh-frozen renal tissue sections (10 µm thick) from the control and CDDP-injected rats. Briefly, after fixation in acetone: methanol (1:1) for 10 min at 4°C, the sections were
incubated with 10% normal goat serum for 30 min. The sections reacted with the primary antibody overnight at 4°C. After rinsing with PBS, the sections were incubated for 45 min with the
following secondary antibodies: Alexa568/anti-mouse IgG1, Alexa488/anti-mouse IgG2a (Invitrogen Co., ×1,000). The sections were visualized with Vectashield mounting medium containing 4ˈ,
6-diamidino-2-phenylindole (DAPI; Vector Laboratories Inc.) for nuclear staining and analyzed using a virtual slide scanner (VS-120, Olympus, Tokyo, Japan).
