Staining was performed using our protocol for IHC Staining with VisUCyte HRP Polymer Detection Reagents.](http://images.novusbio.com/fullsize/HIF-2-alpha-EPAS1-Antibody-2597C-Immunohistochemistry-Paraffin-NBP3-07075-img0001.jpg "Immunohistochemistry-Paraffin: HIF-2 alpha/EPAS1 Antibody (2597C) [NBP3-07075] - HIF-2 alpha /EPAS1 was detected in immersion fixed paraffin-embedded sections of mouse liver using Rabbit Anti-Human HIF-2 alpha /EPAS1 Monoclonal Antibody (Catalog # NBP3-07075) at 3 ug/mL for 1 hour at room temperature followed by incubation with the Anti-Rabbit IgG VisUCyte™ HRP Polymer Antibody (VC003).
