The complete guide to immunohistochemistry
Introduction Immunohistochemistry (IHC) uses antibodies to detect the location of proteins and other antigens in tissue sections The antibody-antigen interaction is visualized using either chromogenic detection with a colored enzyme substrate or fluorescent detection with a fluorescent dye |
When was antigen retrieval first published?
Just two decades have passed since the first article on antigen retrieval (AR) was published in 1991 ( Shi et al. 1991 ).
Which proteins are retrieved from FFPE tissue?
Evidence suggests that many proteins (antigens) “retrieved” from FFPE tissue sections show substantial, if not complete, restoration of immunoreactivity, expressed as an AR efficiency that may approach 100%, exemplified by ER, progesterone receptor (PR), HER-2/neu, p53, and Ki-67 (MIB-1).
How does antigen retrieval work?
Antigen retrieval methods (Table 2) break these methylene bridges and expose antigenic sites, allowing antibodies to bind. Frozen tissue sections are often not robust enough to be used with antigen retrieval without damaging the section.
Does antigen retrieval reverse steric interference caused by formalin-induced cross-links?
