WebFigure 1 Time-dependent decline of microphotometrically assessed reaction rates of SDH in high, intermediate, and low activity fibers of rat extensor digitorum longus muscle. Changes in optical density were recorded from a 9-μm-thick cross-section. Several successive measurements were taken after starting the reaction by applying the assay mixture and … WebIf a single measurement of substrate or product concentration is made after a specified reaction time, a fixed-time assay results. The kinetic assay is more desirable because the time course of the reaction is directly observed and any discrepancy from linearity can be immediately detected. [Pg.287]
