Opal™ is a practical workflow for simultaneous detection of up to 6 tissue biomarkers plus nuclear counterstain, within a single image. The method is similar to standard immunohistochemistry and is accessible to many laboratories where standard IHC method development is performed. Standalone Opal Fluorophore reagent packs allow you to pick and choose your panel's biomarker quantity and design. Spectral DAPI is a nuclear counterstain for use with Opal Multiplex IHC assays. The Opal Reagent Packs can be utilized for both mono- and multiplex tissue staining and have been configured and validated for imaging on the Vectra® and Mantra™ systems. Opal Multiplex IHC Kits make multiplex methods accessible to anyone who works with standard immunohistochemistry. The Opal method allows use of any number of unlabeled primary antibodies from the same species in multiplexed tissue assays, with no fear of cross-reactivity. Antibodies for simultaneous IHC may be selected based on performance, rather than species. The method works with formalin fixed paraffin-embedded (FFPE) tissue and is compatible with the standard research IHC workflow in your lab. Note: If you have never used Opal Multiplex IHC Detection Reagents before, we strongly suggest purchasing the full Opal kit, which includes a set of quality controlled reagents that have been optimized to work together.
