Creatine Kinase Isoenzymes

Clinics in Laboratory Medicine, 1986
Creatine kinase (CK), a widely distributed enzyme in the body, has its highest activities in skeletal muscle and myocardium; when serum CK activities are abnormally increased, injury to these organs must be part of the differential diagnosis. The isoenzyme CK-MB is the most important biochemical test in the diagnosis of acute myocardial infarction.

ISOENZYMES AND ONTOGENY

Biological Reviews, 1972
Summary1. In this review, representative data on the nature of enzyme multiplicity and the developmental progressions of multiple enzyme forms have been collected, and the significance of this material has been discussed in relation to gene involvement during tissue differentiation.2.

Creatine kinase isoenzymes

Journal of Chromatography B: Biomedical Sciences and Applications, 1988
Analytical methods for and the clinical significance of ATP:creatine-N-phosphotransferase (EC 2.7.3.2, CK) isoenzymes have been described. The main assay methods for the isoenzymes are electrophoresis, ion-exchange chromatography and immunoinhibition.

Carcinoplacental isoenzyme antigens

Advances in Enzyme Regulation, 1973
Abstract A carcinoplacental isoenzyme antigen is defined as a catalytically active protein present in a tumor, whose antigenic sites are identical to that of a protein present in the placenta but not in any fetal tissue. A family of placental isoenzymes of alkaline phosphatase (the Regan isoenzyme, the Nagao isoenzyme and Regan variant isoenzyme) is ...

Nihon rinsho. Japanese journal of clinical medicine, 1996
Expression of cancerous isoenzymes in various malignant tumors has been extensively studied using different biochemical techniques. Cancerous alkaline phosphatase (ALP) isoenzymes, such as placental ALP and variant ALP, are detected from sera of patients with various malignant diseases.

Aspartate aminotransferase isoenzymes

Clinical Biochemistry, 1990
Aspartate aminotransferase (AST, EC 2.6.1.1) exists in human tissues as two distinct isoenzymes, one located in the cytoplasm (c-AST), and the other in mitochondria (m-AST). Striated muscle, myocardium, and liver tissues are the main sources of AST. A growing body of information suggests that determination of AST isoenzymes in human serum is useful in ...

Lung Phosphodiesterase Isoenzymes

1993
The distinct phosphodiesterase isoenzyme activities in guinea-pig lung were identified and characterised. We demonstrate that protein kinase A catalyses the activation of lung Type V cyclic GMP phosphodiesterase. This occurs via a marked change in the Vmax for cyclic GMP hydrolysis.

Lactate dehydrogenase isoenzymes

Journal of Chromatography B: Biomedical Sciences and Applications, 1988
The analytical procedures for LD isoenzymes include electrophoresis, chromatography, immunochemical and kinetic methods. Electrophoretic methods are generally preferred because the resulting patterns are directly observable and all five isoenzymes are resolved in a single procedure.

[Isoenzymes].

Die Naturwissenschaften, 1987
Isoenzymes, especially non-allelic forms, are enzyme variants with different primary structure, apparently adapted during phylogeny to distinct physiological conditions. They are ideal research objects either for studies of structure-function relationship and morphogenesis in vertebrates or as diagnostic indicators for pathological processes.
