Antigen Retrieval technique
2017Co-Authors: Shan Rong Shi, Richard J Cote, Clive R TaylorAbstract:Development of the Antigen Retrieval (AR) technique, a simple method of boiling archival paraffin-embedded tissue sections in water to enhance the signal of immunohistochemistry (IHC), was the fruit of pioneering efforts guided by the philosophy of rendering IHC applicable to routine formalin-fixed, paraffin-embedded tissues for wide application of IHC in research and clinical pathology. On the basis of thousands of articles and many reviews, a book has recently been published that summarizes basic principles for practice and further development of the AR technique. Major topics with respect to several critical issues, such as the definition, application, technical principles, and further studies of the AR technique, are highlighted in this article. In particular, a further application of the heat-induced Retrieval approach for sufficient extraction of nucleic acids in addition to proteins, and standardization of routine IHC based on the AR technique in terms of a test battery approach, are also addressed. Furthermore, understanding the mechanism of the AR technique may shed light on facilitating the development of molecular morphology.

Antigen Retrieval immunohistochemistry review and future prospects in research and diagnosis over two decades
Journal of Histochemistry and Cytochemistry, 2011Co-Authors: Clive R Taylor, Shan Rong Shi, Yan ShiAbstract: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 paraffin-embedded (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.

mechanical compression of coverslipped tissue sections during heat induced Antigen Retrieval prevents section detachment and preserves tissue morphology
Journal of Histochemistry and Cytochemistry, 2019Co-Authors: Andreas H. Eckhard, Joseph B. Nadol, Joe C. Adams, Jennifer T OmalleyAbstract:Heat-induced Antigen Retrieval (HIAR) is routinely employed on aldehyde-fixed tissue sections to enhance the reactivity of antibodies that exhibit weak or no specific interactions with tissue Antigens when applied in conventional immunohistochemical protocols. A major drawback of HIAR protocols is, however, the heat-induced detachment of sections from the microscope slide with resultant impaired tissue morphology or loss of the section. We developed a method in which tissue sections mounted on glass slides are temporally coverslipped, and a clamp is used to compress the sections on the microscope slide during HIAR treatment. This "pressurized coverslipping" during HIAR was tested on various formalin-fixed tissues (murine kidneys and temporal bones, human tonsils and temporal bones) that were embedded in paraffin or celloidin. The method reliably kept the sections adherent to the slide, preserved the tissue morphology, and effectively retrieved tissue Antigens for improved results in immunohistochemical labeling, even for exceptionally delicate, large, and poorly adhering sections, that is, decalcified human temporal bone sections. In summary, we present a simple method for improved slide adherence and morphological preservation of tissue sections during HIAR treatment that can be combined with all HIAR protocols and that requires only basic lab equipment.

dna extraction from archival formalin fixed paraffin embedded tissue sections based on the Antigen Retrieval principle heating under the influence of ph
Journal of Histochemistry and Cytochemistry, 2002Co-Authors: Richard J Cote, Lin Wu, Ram H Datar, Clive R TaylorAbstract:During the course of diagnostic surgical pathology, pathologists have established a large collection of formalin-fixed, paraffin-embedded tissues that form invaluable resources for translational studies of cancer and a variety of other diseases. Accessibility of macromolecules in the fixed tissue specimens is a critical issue as exemplified by heat-induced Antigen Retrieval (AR) immunohistochemical (IHC) staining. On the basis of observations that heating may also enhance in situ hybridization (ISH) and the similarity of formalin-induced chemical modifications that occur in protein and in DNA, we designed a study to examine the efficiency of DNA extraction from archival formalin-fixed, paraffin-embedded tissues using an adaptation of the basic principles of the AR technique, i.e., heating the tissue under the influence of different pH values. Archival paraffin blocks of lymph nodes, tonsil, and colon were randomly selected. Each paraffin block was prepared in 34 microtubes. For each paraffin block, one tu...

Antigen Retrieval immunohistochemistry and molecular morphology in the year 2001
Applied Immunohistochemistry & Molecular Morphology, 2001Co-Authors: Shan Rong Shi, Richard J Cote, Clive R TaylorAbstract:The impact of the Antigen Retrieval (AR) technique upon diagnostic immunohistochemistry (IHC) and upon research has been demonstrated by numerous of articles and more than a dozen major reviews. The specific aim of this survey of the field is to examine potential new approaches to Retrieval of nucleic acid and protein from archival paraffin-embedded tissue for molecular biology-based diagnostic procedures that form the basis of the emerging field of molecular morphology. Any new approach must incorporate the principles of standardization and improved reproducibility. The ultimate goal will be to understand the mechanisms of fixation (by formalin) and "unfixation" (by AR). In the interim, the diligent application of practical procedures that have been shown to be tried and true is the least that we must demand from ourselves and our laboratories.

Antigen Retrieval immunohistochemistry practice and development
Journal of Histotechnology, 1997Co-Authors: Shan Rong Shi, Richard J Cote, Lillian Young, Clive R TaylorAbstract:AbstractThe Antigen Retrieval (AR) technique is a novel, simple, and reliable approach to routine immunohistochemistry (IHC) developed in 1991. It has increasingly been used in pathology and analytical morphology, with a wide fruitful field opened for both clinical and research projects. Hundreds of articles concerning AR-IHC have been published in a variety of journals all over the world. As a recently developed technique, the wide use of AR has raised numerous questions for further study. This review article focuses on several key points of the method and further developments of the AR technique that are different from some review articles published recently.

Antigen Retrieval immunohistochemistry past present and future
Journal of Histochemistry and Cytochemistry, 1997Co-Authors: Shan Rong Shi, Richard J Cote, Clive R TaylorAbstract:The Antigen Retrieval (AR) technique, which is predominantly based on high-temperature heating of tissues, is used as a non-enzymatic pretreatment for immunohistochemical staining of formalin-fixed, paraffin-embedded tissue sections. It has been widely applied in pathology and analytical morphology. The existence of a growing body of literature on the AR technique raises a number of interesting issues for the further development of AR. These issues include the use of a "test battery" and the concept of "maximal Retrieval" applied to the selection of optimal test protocols for the standardization of AR.
