Immune Chromogenic Reagent (Dual Staining I)

Immune chromogenic reagent (Dual Staining I) is an immunohistochemical detection kit based on two enzyme-labeled micropolymers and can detect 2 to 4 antigen targets on the same sample at the same time. It adopts the "DaulStacker™" polymer with high sensitivity and strong specificity independently developed by the Celnote American team. The kit belongs to a non-biotin detection system and is a dual-color system based on horseradish peroxidase-labeled anti-mouse polymer and alkaline phosphatase labeled anti-rabbit polymer. The Chromogen system of horseradish peroxidase is DAB showed tawny or brown, but that of alkaline phosphatase is fast red showed red color. However,during the usage of this kit, it should be paid attention to the selection of antibodies to avoid overlapping of the detected antigen targets on the tissue and inconsistent antigen repairing conditions.
