Webreaction. This can be done in several ways—reducing the concentration of tyramide or peroxidase conjugate applied to the specimen or shortening the reaction time. The use of streptavidin–HRP as the secondary detection reagent can result in mitochondrial staining of the endogenous biotinylated mitochondrial proteins.13 Webbiotin concentration in the reaction mixture to the biotin concentration in the original sample. If the original sample was diluted before performing the assay, then the dilution factor must be used as well. Calculation #4 yields the biotin:protein molar ratio (average # of biotin molecules per protein molecule). greenock and paisley presbytery
