WebChemiluminescent substrates for horseradish peroxidase (HRP) are important tools in the immunodetection of target proteins and antigens, particularly in Western blotting. Substrates such as ECL (Enhanced Chemiluminescence) function by producing light in the presence of HRP and hydrogen peroxide. 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 … See more The enzyme horseradish peroxidase (HRP), found in the roots of horseradish, is used extensively in biochemistry applications. It is a metalloenzyme with many isoforms, of which the most studied type is C.
