Anti-NSE immunostaining is also positive in normal striated muscle, hepatocytes and, to a lesser extent, smooth muscle.⁴ Anti-NSE is a useful marker to identify peripheral nerves.⁵ When used for the identification of neuroendocrine differentiation, it is suggested that it be employed in a panel with more specific markers such as antisynaptophysin, anti-chromogranin, and anti-neurofilament.

In general, immunohistochemical staining allows the visualization of antigens via the sequential application of a specific antibody (primary antibody) to the antigen, a secondary antibody (link antibody) to the primary antibody, an enzyme complex and a chromogenic substrate with interposed washing steps. The enzymatic activation of the chromogen results in a visible reaction product at the antigen site. The specimen may then be counterstained and a coverslip applied. Results are interpreted using a light microscope and aid in the differential diagnosis of pathophysiological processes, which may or may not be associated with a particular antigen.

This antibody is optimally diluted to be compatible with VENTANA detection kits and BenchMark IHC/ISH instruments. Refer to the Tables in the Instructions for Use section for recommended staining protocols. Each step in the staining protocol includes incubation for a precise time at a specifi c temperature. At the end of each incubation step, the sections are rinsed by the BenchMark IHC/ISH instruments to stop the reaction and remove unbound material that would hinder the desired reaction in subsequent steps. To minimize evaporation of the aqueous reagents from the specimen-containing slide, a coverslip solution is applied in the slide stainer.
