Trypsin Digestion solution [0.1%]

Trypsin 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. Trypsin digestion improves immunoreactivity of some antigens in FFPE tissue sections.
