Creatine kinase (CK)—also known as creatine phosphokinase (CPK) or phospho-creatine kinase—is an enzyme (EC 2.7.3.2) expressed by various tissues and cell types. CK catalyses the conversion of creatine and utilizes adenosine triphosphate (ATP) to create phosphocreatine (PCr) and adenosine diphosphate (ADP). This CK enzyme reaction is reversible and thus ATP can be generated from PCr and ADP. In tissues and cells that consume ATP rapidly, especially skeletal muscle, but also brain, photoreceptor cells of the retina, hair cells of the inner ear, spermatozoa and smooth muscle, PCr serves as an energy reservoir for the rapid buffering and regeneration of ATP in situ, as well as for intracellular energy transport by the PCr shuttle or circuit. Thus creatine kinase is an important enzyme in such tissues. Clinically, creatine kinase is assayed in blood tests as a marker of damage of CK-rich tissue such as in myocardial infarction (heart attack), rhabdomyolysis (severe muscle breakdown), muscular dystrophy, autoimmune myositides, and acute kidney injury.
Human Creatine kinase BB isoenzyme (CK-BB) ELISA Kit employs a two-site sandwich ELISA to quantitate CK-BB in samples. An antibody specific for CK-BB has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyCK-BB present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CK-BB is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CK-BB bound in the initial step. The color development is stopped and the intensity of the color is measured.
