14 Ischemia-Fixation TMA Pre-analytic variables in FFPE Varied duration from devascularization to preservation: ISCHEMIA time (minutes to hours) Varied duration of fixation: 0- 36 hours Varied tissue processor protocols across institutions Design: Timed experiment with varied ischemia/fixation times of tissue –constituted into TMA (n = 3+) Outcome: TMA slides for 1) investigators to measure preservation of marker of interest against different pre-analytic variables 2) NMVB biospecimen science – to determine biomarkers that reflect early ischemic effects for rating of core preservation on NMVB TMAs.

16 Diagnostic marker durability: Necrosis, ischemia, overfixation (WT-1, Calretinin) (autopsy vs biopsy material) Impact of preanalytic variables: Tissue expression of current serum /pleural fluid biomarkers: Tools: Frozen TMA & Ischemia/Fixation TMA Biospecimen Science
