SMAC/Diablo in Human Prostate. SMAC/Diablo was detected in immersion fixed paraffin-embedded sections of human prostate using Goat Anti-Human SMAC/Diablo Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7891) at 1.7 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Goat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS008) and counterstained with hematoxylin (blue). Specific labeling was localized to the cytoplasm of glandular epithelial cells. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.
Detection of Human SMAC/Diablo by Western Blot. Western blot shows lysates of SH‑SY5Y human neuroblastoma cell line, mouse NB41A3 mouse neuroblastoma cell line, and PC‑12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.5 µg/mL of Goat Anti-Human SMAC/Diablo Antigen Affinity-purified Polyclonal Antibody (Catalog # AF7891) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SMAC/Diablo at approximately 22 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
