Biosystems Creatinkinaz Reagent


Creatine kinase (CK) catalyzes the phosphorylation of ADP, in the presence of creatine phosphate, to form ATP and creatine.

The catalytic concentration is determined from the rate of

NADPH formation, measured at 340 nm, by means of the hexokinase (HK) and glucose-6- phosphate dehydrogenase (G6P-DH) coupled reactions1,2


A. Reagent: Imidazol 125 mmol/L, EDTA 2 mmol/L, magnesium acetate 12.5 mmol/L, Dglucose 25 mmol/L, N-acetyl cysteine 25 mmol/L, hexokinase 6000 U/L, NADP 2.4 mmol/L,
pH 6.7.

  1. Reagent: Creatine phosphate 250 mmol/L, ADP 15 mmol/L, AMP 25 mmol/L, P1,P5-di(adenosine-5′-)pentaphosphate, 102 µmol/L, glucose-6-phosphate dehydrogenase
    8000 U/L.
