Indirect Immunofluorescence of Tissue Sections

Immunofluorescence (IF) on tissue sections allows for the detection of protein species subcellular localization. IF studies further offer the ability to achieve this understanding at the level of single cell granularity. Here, we describe the processes by which tissue is fixed, embedded, sectioned, and subsequently utilized for conducting indirect IF assays. We raise potential opportunities for troubleshooting and optimization at varying stages of the protocol.
