Pepsin Reagent (Ready to Use), MIT-HCl

Pepsin is an antigen retriever solution used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. Formulation meets EU requirements. Pepsin is an antigen retriever solution 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. This formulation is free from restricted preservatives and is compliant with EU regulations.
