Sensitive, rapid, and quantitative methods have been devised for the assay of cellulases and dextranases through the synthesis of two chemically modified carboxymethyl cellulose substrates. One contains a trinitrophenyl group as chromophore. The other contains a fluorescent fluorescamine group. The

β¦ Synopsis
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 cellobiase-producing enzymes as well as a measure of cellobiose degradation by (5glucosidases. This assay shows a 20-fold increase in sensitivity over the traditional reducing sugar assay.

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 a
A new kinetic method is described for the assay of quinone-reducing enzymes in various biological materials. It is based on polarographic determination of oxygen uptake in spontaneous oxidation of the diphenol formed as a result of 4-anilino-5-methoxybenzoquinone-1 ,2 (AMOBQ) enzymic reduction. The
