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


  • Use as antigen retriever for some antibodies in IHC
  • Please refer to primary antibody protocol for IHC
  • Supplied as concentrated form along with buffer


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. Trypsin digestion improves immunoreactivity of some antigens in FFPE tissue sections. For cytokeratin clone AE3 and AE1/AE3, this enzyme works much better than boiling the tissue with citrate buffer.


Delivery information: Small kit contains (15 mL) Reagent B Buffer and (2 mL) Reagent E (Enzyme).
