You Searched For: Enzymes

Enzymes accelerate, or catalyse, chemical reactions, and they are known to catalyse more than 5,000 biochemical reaction types. Most enzymes are proteins, although a few are catalytic RNA molecules. Choose specific enzymes for cleaving bonds, removing genomic DNA from RNA preparations, for producing fragments of proteins, or for use in ion exchange chromatography. Enzymes are used in the chemical industry and other industrial applications when extremely specific catalysts are required.

Pig Pepsin (from Stomach)

Supplier: SIGMA-ALDRICH MICROSCOPY
Description: Pepsin is used for proteolytic digestion of formalin-fixed paraffin-embedded (FFPE) tissue sections prior to application of antibodies. In immunohistochemistry (IHC), 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 accessibility of antibodies to tissue antigens. Ready to use pepsin reagent, antigen retriever has been used for antigen unmasking in immunohistochemistry.

Histo/Zyme

Supplier: SIGMA-ALDRICH MICROSCOPY
Description: Histo/Zyme is a stabilized proteolytic enzyme in buffered solution, used to unmask immunoreactive sites altered by fixation and/or the embedding process. Treatment with a proteolytic enzyme in immunohistochemistry (IHC) is required to digest excess linkages and expose the antigen. The use of Histo/Zyme results in superior staining over traditionally used enzyme pretreatments, such as pepsin and trypsin. Moreover, Histo/Zyme requires only a brief incubation at room temperature. Performing antigen recovery with Histo/Zyme will allow you to dilute the primary antibody 5 to 10 fold further and achieve optimal staining.
