Creatine Kinase Assay Kit is a colorimetric determination of creatine kinase activity at 340 nm.
CREATINE KINASE (CK), also known as creatine phosphokinase (CPK), is an enzyme (EC 184.108.40.206) expressed predominantly in skeletal muscle, smooth muscle and the brain. The CK enzyme consists of two subunits, which can be either B (brain type) or M (muscle type), and hence three different isoenzymes: CK-MM, CK-BB and CK-MB. CK catalyzes the conversion of creatine to phosphocreatine, consuming adenosine triphosphate (ATP) and generating adenosine diphosphate (ADP) and the reverse reaction. CK is often determined routinely in emergency patients with chest pain and acute renal failure. Elevation of CK is an indication of damage to muscle and has been associated with injury, rhabdomyolysis, myocardial infarction, myositis, myocarditis, malignant hyperthermia and neuroleptic malignant syndrome, etc. Lower levels can be an indication of alcoholic liver disease and rheumatoid arthritis.
Direct Assays: CK in serum, plasma and other biological samples.Pharmacology: effects of drugs on CK activity.
