Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies.


  • Antigen retriever for some antibodies in IHC
  • Please refer to primary antibody protocol for IHC


Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In IHC most commonly used fixative like formalin mask tissue antigens (cellular, membrane and nuclear) by cross-linking process, this results in poor or no staining in IHC.


Pepsin digestion of FFPE tissue section improves accessibility of antibodies to tissue antigens.
