The UltraTek line is our leading edge system, designed to provide optimal staining with incubation times of 10 minutes each for the link antibody and enzyme label. UltraTek Anti-Polyvalent is specially formulated and optimized to be used in a labeled streptavidin-biotin immunoenzymatic antigen detection system. This technique requires the sequential incubation of the specimen with an unconjugated primary antibody specific to the target antigen, a biotinylated secondary antibody which reacts with the primary antibody, enzyme-labeled streptavidin, and substrate-chromogen. For most procedures, commercially available primary antibodies can be diluted up to 50% more than with other systems.Summary Protocol:Incubate on tissue section after application of the primary antibody. PolyTek，抗兔聚合HRP已开发，具有成本效益，可提供最清洁，最一致的染色。该系统基于聚合的过氧化物酶标记，该标记从等式中消除了生物素，从而消除了背景染色的主要原因。
