Synaptophysin antibody

Positive Control: Colon: A moderate to strong staining of the axons of the Auerbach’s and Meissner’s plexus should be seen while the endocrine cells of the mucosa and the peripheral nerves in the mucosa must show an at least a weak to moderate staining. Pancreas: A strong staining should be seen in islets of Langerhans and in peripheral nerve fibres located between the exocrine cells. Negative Control: Colon: All non-endocrine epithelial cells and lymphocytes should not show any staining. Cellular Localization: Cytoplasmic Protocol Recommendations: Manual Protocol: Freshly cut sections should be used (less than 10 days between cutting and staining) . Heat-induced antigen retrieval for 5 minutes in an autoclave at 121°C in pH 7.8 Target Retrieval Solution buffer. Apply the antibody at a dilution of 1:150 at 37°C for 60 minutes. Visualization of bound antibody by the EnVision Kit (Dako, Agilent) according to the manufacturer’s directions.
