Research on the mechanism of action of cellulases has been hampered by the lack of a rapid, continuous, or kinetic assay. A linked assay system that uses glucose oxidase and horseradish peroxidase has been coupled with @-glucosidase to yield an assay system that can be used for kinetic assays for ce

โฆ Synopsis
Using glycerol kinase and [3H]glycerol, a kinetic isotope dilution assay for glycerol has been developed. Reactant and product are separated by stepwise elution from QAE-Sephadex. This assay is sensitive to as little as 100 pmol of glycerol, avoids numerous drawbacks of the traditional fluorescent assay, and readily detects glycerol production by fewer than 10(5) cardiomyocytes.

We have developed a new assay for purine nucleoside phosphorylase which is based on the release of tritium when [2-3H]inosine is used as the substrate and the reaction is coupled with xanthine oxidase. After the reaction is terminated, residual [2-3H]inosine is adsorbed on charcoal and the supernata
