Web8 Mar 2016 · Biotinylated secondary antibody and streptavidin-HRP are commonly used in the ELISA to improve the limit of detection (LOD). Streptavidin is a tetrameric protein with a molecular weight of 60 kDa; it has a high binding affinity to biotin (in the low femtomolar range) and four biotin binding sites [ 36 ]. WebBoth AP and HRP can be conjugated with avidin or biotin for use in avidin biotin signal amplification systems. ... immunochemistry or ELISA. HRP is a heme containing enzyme that catalyses the oxidation of luminol resulting in low intensity light emission at 428. This light emission can be enhanced by a 100 fold by adding certain chemicals.
