Product Description:

Pyruvate kinase (PK) catalyzes the last step of aerobic glycolysis, converting phosphoenolpyruvate (PEP) to pyruvate with production of one ATP. Liver PK is subject to hormonal and allosteric regulation, which is involved in maintaining blood glucose homeostasis. The importance of this substrate-level phosphorylation step is underscored by the finding that PK deficiency, one of the most common enzymopathies, manifests clinically as hemolytic anemia. The clinical severity of PK deficiency varies widely, ranging from a mildly compensated anemia to severe childhood anemia. In addition, PK isoform switch is known to promote tumorigenesis. The enzyme activity assay kit can measure PK activity present in serum/plasma and crude cell/tissue extracts. Luciferase-based detection of ATP produced by PK reaction allows fast, sensitive and quantitative assay of PK activity. Measurement of ATP requires a luminometer or scintillation counter. Kit components are stable for many years if stored and handled properly.
