The enzyme from horseradish is a glycoprotein, MW approximately 44 kDa, with hemin prosthetic group and bound Ca++. The RZ (Reinheitszahl) is the absorbance ratio A403/A275 determined at 0.5-1.0 mg/ml in deionized water. It is a measure of hemin content, and not enzymatic activity.
10 mM phosphate, 200 mM NaCl (pH 7.4), 10 mg/ml BSA, 0.05% Proclin 300.
Store as concentrated solution. Centrifuge briefly prior to opening vial. Store at 4º C.
