FFPE
Formalin Fixed Paraffin Embedded (FFPE) is a form of preservation and preparation for biopsy specimens to help in diagnostic examination, experimental research, and diagnostic/drug development. A tissue sample is first preserved by fixing it in formaldehyde, which preserves the proteins and vital structures within the tissue. The tissue is then embedded in paraffin wax to support the tissue structure and enable very thin sections to be cut and mounted onto microscope slides for analysis.
