This enzyme is useful for enzymatic determination of H₂O₂ in clinical analysis. Especially, the highly purified preparation (Grade I) is useful as a protein tracer in histo-and cyto-chemistry and as a valuable experimental tool in hodological neurography. Also, the enzyme preparation has been used as an enzyme label in enzyme immunoassay. Grade III is suitable for dry chemistry. On the other hand, the enzymes contribute for the reduction of phehol in waste water.
