Fluorescent horseradish peroxidase substrates
WebApr 8, 2024 · Protease tags, such as horseradish peroxidase (HRP) and lactate dehydrogenase , exert efficient and specific substrate catalytic properties to achieve highly sensitive signal output through fluorescent and colorimetric platforms . However, due to the uncontrolled catalytic activity of protease tag, ELISA technique and others requires … WebPeroxidase catalyses the reduction of hydrogen peroxide to generate two water molecules. TMBZ is the electron source for this reduction. Since the oxidized forms of TMBZ have intense colors, peroxidase can be determined colorimetrically. Horseradish peroxidase (HRP) is widely applied in EIA and diagnostic analyses.
