Survey of serum enzyme analyses. Human tissues as a source of enzymes
Abstract:
The College of American Pathologists' enzyme survey permits the evaluation of the quality of enzyme analyses in clinical laboratories. Animal source enzymes for lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, and creatine kinase are satisfactory as supplements for enzyme survey serum, since they give results equivalent to human source enzymes. This finding makes the interconversion of results by different methods possible, and the estimation of the upper limit of normal based on the results obtained for the enzyme survey serum.

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
Enzyme Kinetics
Scientists typically study enzyme kinetics with a fixed amount of enzyme in the controlled environment of a test tube. When more reactant, or substrate, is...
Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
