Web• Sensitive one-step assay to detect hydrogen peroxide or peroxidase in vitro • Can detect as little as 10 picomoles of hydrogen peroxide or 10 µU/mL of horseradish peroxidase activity in a 100 µL assay volume • Provides sufficient reagents for approximately 500 assays using reaction volumes of 100 µL per assay WebDec 12, 2012 · A molecular design of CRET was typically elucidated by conjugation of an energy donor (e.g., horseradish peroxidase (HRP)) and an energy acceptor (e.g., QDs). For example, gold nanoparticle (AuNP) based CRET systems have been reported previously. In the probe design, AuNP and HRP were conjugated to two different antibodies.
WebNational Center for Biotechnology Information Horseradish peroxidase is a 44,173.9-dalton glycoprotein with 6 lysine residues which can be conjugated to a labeled molecule. It produces a coloured, fluorimetric, or luminescent derivative of the labeled molecule when incubated with a proper substrate, allowing it to be detected and quantified. HRP is often used in conjugates (molecules that have been joined genetically or chemically) to determine the presence of a molecular target. For example, an antibody conjugate…
