Description

Analysis Note

Protein determined by Lowry method.

Biochem/physiol Actions

Lactoperoxidase catalyzes the oxidation of iodide to iodine by hydrogen peroxide. This activity provides a gentle, specific alternative to chloramine T for the radioiodination of proteins and DNA.

Other Notes

Using 2,2′-azinobis(3-ethylbenzthiazoline-6-sulfonic acid) diammonium salt as substrate, two or three times the activity is observed.

Unit Definition

One unit will form 1.0 mg of purpurogallin from pyrogallol in 20 sec at pH 6.0 at 20 °C.
