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.
