17 beta -HSD14/HSD17B14 in Human Brain. 17 beta -HSD14/HSD17B14 was detected in immersion fixed paraffin-embedded sections of human brain (medulla) using Mouse Anti-Human 17 beta -HSD14/HSD17B14 Monoclonal Antibody (Catalog # MAB7515) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013 ). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002 ) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cytoplasm. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections .
