Knowledge Tissue Processing Protocols 0 Endorse Having an effective tissue processing protocol is important for a number of good reasons. With its upstream situation from the histopathology course of action, inefficient tissue processing may have damaging ramifications by the rest of the downstream method from embedding to staining, pathology critique and imaging.
