Rapid kinetic microassay for catalase activity.
Catalase is a commonly assayed enzyme found in many bacteria and eukaryotes. In this report, we examined the applicability of a kinetic microassay to quantify catalase from two different sources. The assay was found to be linear over a wide range (0.1-1.0 units), but was limited at high values (>1 unit) by oxygen evolution. Nonetheless, the microassay allows simultaneous evaluation of many samples (up to 96) in a short time (<5 min) and is thus well-suited to applications, such as high-throughput screening, where many parallel assays are required.
