ARExVisual® Chromogens represent a class of specialized chromogenic substrates engineered for immunohistochemical detection in both diagnostic and research pathology. Acting as key downstream reporters in the IHC workflow, they react specifically with reporter enzymes such as horseradish peroxidase (HRP) and alkaline phosphatase (AP) to generate intense, permanent color precipitates that are firmly bound to the target antigens.
Optimized for a wide range of sample types—including formalin-fixed paraffin-embedded (FFPE) tissues, frozen sections, and cytological preparations—these chromogens provide high-contrast, stable color development with minimal non-specific background. Their excellent compatibility with counterstaining and long-term tissue archiving makes them ideal for precise morphological evaluation, accurate biomarker localization, and reliable semi-quantitative analysis.

Key Advantages:

・Intense Signal & Low Background: Produce sharp, distinct color signals with excellent signal-to-noise ratio.
・High Stability: Color precipitates remain stable for long-term storage and archiving.
・Broad Compatibility: Suitable for both manual and automated IHC platforms, with strong performance across HRP and AP detection systems.
・Versatile Applications: Widely used in oncology, inflammatory disease research, neuroscience, and translational pathology to support biomarker discovery and clinical diagnostics.

As indispensable supporting reagents in complete IHC staining workflows, ARExVisual® Chromogens significantly enhance assay reliability, result interpretability, and overall workflow efficiency for both routine clinical pathology and advanced scientific research.
