Detection Principle Creatine kinase (CK) catalyze creatine phosphate and ADP to produce creatine and ATP. Hexokinase catalyze creatine and glucose to produce glucose-6-phosphate. Glucose-6-phosphate dehydrogenase (G-6-PD) catalyze glucose-6-phosphate and NADP+ to produce NADPH which have a maximum absorption peak at 340 nm. The CK activity can be calculated by measuring the OD values at 340 nm.

The recommended dilution factor for different samples is as follows (for reference only):

Sample Type Dilution Factor
Human serum 1
Human plasma 1
Mouse serum 1
Rat serum 1
HepG2 cells homogenization 1
10% Rat kidney tissue homogenization 1
10% Rat brain tissue homogenization 2-5
10% Rat liver tissue homogenization 2-10

The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4). For the dilution of other sample types, please do pretest to confirm the dilution factor.
