A highly sensitive chemiluminescent assay for NAD(P)H have been developed. The principle of the method is as follows; NAD(P)H reduces molecular oxygen t o superoxide anion (0;) and hydrogen peroxide (H202) in the presence of I-methoxy-5-methylphenazinium methyl sulphate (I-MPMS) as electron mediator

β¦ Synopsis
A wide range of luminescent assays for enzyme labels has been developed. The clinical application of luminescent assays for horseradish peroxidase, alkaline phosphatase, xanthine oxidase, beta-D galactosidase, and glucose 6-phosphate dehydrogenase is discussed. The enzyme luminescent methods provide improved sensitivity compared with colorimetric and fluorimetric assays. A new reagent, dioxetane phosphate, has provided a simple and extremely sensitive assay for alkaline phosphatase. The available instruments and new photographic detection techniques for luminescent assays are briefly discussed.

A solid-phase enzyme-linked immunosorbent assay (ELISA) with monoclonal secondary antibodies was used to detect matrix protein and nucleoprotein of influenza A. The sensitivity of the ELISA for highly purified A/Brazil nucleoprotein and matrix protein was 0.05 and 1.0 ng, respectively. Nasal washes
We designed a rapid, homogeneous assay for human aspartate aminotransferase (AST) isoenzymes, by a selective proteolysis of soluble AST (s-AST), using chymotrypsin and protease 401. The linearity of mitochondrial (m-AST) was elongated up to 4000 U/I. m-AST values from the human liver, and determined
The colorimetric method for phosphate determination described in the preceding paper is adapted for the assay of orthophosphate liberated in the aspartate transcarbamylase reaction. The method provides for simple, accurate, and sensitive measurement of enzyme activity. The assay uses ammonium molybd
