Bio-Techne’s VisUCyte™ HRP Polymer Detection Kits are an advanced research solution for streamlined and precise tissue staining. Our kits, consisting of biotin-free detection reagents, overcome challenges of avidin-biotin detection chemistry by providing faster and more efficient, specific staining on tissue sections. With the high sensitivity of VisUCyte™ HRP Polymer, primary antibody concentrations can be reduced by 2-3 times compared to conventional methods.
Our HRP polymer-conjugated secondary antibodies are versatile, reacting with all IgG subclasses, suitable for both manual protocols and tissue autostainers. Secondary antibodies used for conjugation to HRP polymer undergo rigorous quality control, ensuring reproducibility. Due to their high sensitivity, VisUCyte™ kits are ideal for detecting low-abundant tissue proteins, providing the ability to complete IHC experiments in just 1-2 hours, while additionally resulting in significant cost savings.

Scientific Data Examples for Rabbit VisUCyte HRP Polymer-DAB Cell & Tissue Staining Kit
Detection of Ki67/MKI67 in Kidney Tumor.
Tissue sections were first incubated with Human Ki67/MKI67 Antibody (MAB7617) and then subjected to staining development using Rabbit IgG VisUCyte HRP-DAB Kit (Catalog # VCTS003B). Specific staining was localized to the nucleus. Note strong and high contrast specific tissue staining and the absence of non-specific background staining produced by the VisUCyte kit.
Detection of ErbB2/Her2 in human breast cancer
Tissue sections were first incubated with Rabbit Anti-Human Phospho-ErbB2/Her2 Polyclonal Antibody (AF1768) and then subjected to staining development using Rabbit VisUCyte Detection kit (Catalog# VCTS003B). Staining is confined to the cell membranes of cancer cells. Note strong and high contrast specific tissue staining and the absence of non-specific background staining produced by the VisUCyte kit.
Side-by-side comparison of staining using different detection chemistries on adjacent tissue sections of Human Colon Tumor.
Ki67/MKI67 was detected in immersion fixed paraffin-embedded sections of human colon tumor using Rabbit Anti-Human Ki67/MKI67 Monoclonal Antibody (Catalog # MAB7617) at 1 µg/ml for overnight at 4 °C followed by incubation with the Rabbit VisUCyte HRP Polymer-DAB Cell & Tissue Staining Kit (Catalog # VCTS003B) and a generic Avidin-Biotin kit. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to the membrane. Strong specific tissue staining is seen using VisUCyte kit.
