Product Description
General description
Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to the application of antibodies. In immunohistochemistry (IHC), the most commonly used fixatives such as formalin mask tissue antigens (cellular, membrane, and nuclear) by their intrinsic crosslinking. This masking results in poor or no staining in IHC. Pepsin digestion of FFPE tissue sections improves the accessibility of antibodies to tissue antigens. Ready to use pepsin reagent, antigen retriever has been used for antigen unmasking in immunohistochemistry.
Application
在免疫组化（IHC）中应用抗体之前，胃蛋白酶用于福尔马林固定石蜡包埋（FFPE）组织切片的蛋白水解消化。
