Fluorescent horseradish peroxidase substrates
WebHorseradish peroxidase (HRP) is an enzyme that specifically reduces hydrogen peroxide in the presence of a proton-donor. HRP is a 40 kDa glycoprotein. The optimal pH range for activity is 6.0-6.5. HRP exhibits good thermal stability (up to 60 0 C) and pH stability (4-10). It is inhibited by azide.
