Horseradish peroxidase

Horseradish peroxidase (HRP) is a glycoprotein that is absent from most mammalian cells. It can be employed as both a fluid-phase and receptor-mediated probe. HRP was demonstrated to be a ligand for MR (Stahl et al., 1978). It is a convenient tracer for immunocytochemistry; in situ, HRP can be detected by reaction with diamino-benzidine Horseradish Peroxidase is a metalloenzyme that exists in the root of the horseradish plant. There are a large number of peroxidase isoenzymes of horseradish with the most common being the C type. 1 This type will be discussed in the remaining report because of the extensive research that has been completed on it
