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 specific 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. For more detailed information on instrument operation, refer to the appropriate BenchMark IHC/ISH instruments Operator’s Manual.", "Language": "en", "Country": "XG", "Code": "Principle" }, { "Name": "Product Purpose", "Value": "WT1 (6F-H2) Mouse Monoclonal Primary Antibody is intended for laboratory use in the detection of the WT1 protein in formalin-fixed, paraffin-embedded human tissue stained in qualitative immunohistochemistry (IHC) on BenchMark IHC/ISH instruments.
