Summary
As a review for the 20th anniversary of publishing the antigen retrieval (AR) technique in this journal, the authors intend
briefly to summarize developments in AR-immunohistochemistry (IHC)–based research and diagnostics, with particular
emphasis on current challenges and future research directions. Over the past 20 years, the efforts of many different
investigators have coalesced in extending the AR approach to all areas of anatomic pathology diagnosis and research and
further have led to AR-based protein extraction techniques and tissue-based proteomics. As a result, formalin-fixed paraffinembedded
(FFPE) archival tissue collections are now seen as a literal treasure of materials for clinical and translational
research to an extent unimaginable just two decades ago. Further research in AR-IHC is likely to focus on tissue proteomics,
developing a more efficient protocol for protein extraction from FFPE tissue based on the AR principle, and combining the
proteomics approach with AR-IHC to establish a practical, sophisticated platform for identifying and using biomarkers in
personalized medicine. (J Histochem Cytochem 59:13–32, 2011)
