This video demonstrates an assay to perform multiplex immunostaining using primary antibodies from the same host species. In this method, an adrenal tissue section undergoes a two-step immunostaining process. Initially, the section is stained with antibodies specific for markers in the cortex, followed by stripping the bound antibody and restaining with antibodies specific for markers in the medulla.
Protocol
All procedures involving sample collection have been performed in accordance with the institute's IRB guidelines. 1. Staining with the First Antibody Dewax and rehydrate formalin-fixed paraffin-embedded (FFPE) slides with 5 min allotted to each of the following steps: xylene or equivalent reagents 3x, 100% ethanol 2x, 95% ethanol 1x, 70% ethanol 1x, 50% ethanol 1x, and distilled water 2x. NOTE: Slides should remain moist starting from th…
