A new serum alpha-amylase assay of high sensitivity. 1977

J J Marshall, and A P Iodice, and W J Whelan

The use of chemically modified starch substrates for measurement of serum alpha-amylase activity is described. Action of alpha-amylase on such substrates, in the presence of excess fungal glucoamylase, results in the production of glucose in direct proportion to the amount of alpha-amylase present. The glucose produced is measured by a specific enzymic assay. Results obtained by using this new assay correlate well with activities determined by a conventional saccharogenic assay. The new method is of much higher sensitivity, and is less susceptible to interference, than are most other alpha-amylase assay methods.

D010084 Oxidation-Reduction A chemical reaction in which an electron is transferred from one molecule to another. The electron-donating molecule is the reducing agent or reductant; the electron-accepting molecule is the oxidizing agent or oxidant. Reducing and oxidizing agents function as conjugate reductant-oxidant pairs or redox pairs (Lehninger, Principles of Biochemistry, 1982, p471). Redox,Oxidation Reduction
