Omnimap goat anti rabbit hrp

Tryptase was used to detect MCs; CD34 staining, an endothelial cell marker, was used to visualize the glomerular and tubular interstitial compartments. The corresponding second section of each biopsy was stained by chromogenic multiplex staining: briefly, after de-paraffinization, CC1 (#950-124; Ventana Medical Systems, Tucson, AZ) antigen retrieval was performed for 64 min at 95°C, followed by incubation for 8 min with the Discovery inhibitor (#760-4840; Ventana Medical Systems). Primary antibody CD34 (#790-2927; Ventana Medical Systems) was incubated for 32 min at 37°C, followed by detection with OmniMap goat-anti-rabbit HRP (#760-4311; Ventana Medical Systems), and visualized using purple kit for 32 min. A CC2 (#950-123, Ventana Medical Systems) 100°C stripping step was performed for 8 min. Tryptase (#760-4276; Ventana Medical Systems) was incubated at 37°C for 32 min, followed by secondary antibody, OmniMap goat-anti-mouse HRP (#760-4310; Ventana Medical Systems) at 37°C for 24 min, and visualized with 3,3′-Diaminobenzidine (#760-229; Ventana Medical Systems) for 32 min. Finally, Hematoxylin II (#790-2208; Ventana Medical Systems) was used to counter stain for 8 min and then a blue coloring reagent (#760-2037; Ventana Medical Systems) for 4 min according to the manufactures instructions (Ventana Medical Systems).
