WebbAbstract. A kinetic method for the assay of urease and urea is reported. The method measures the change of absorbance with time of the indicator phenol red. The change in absorbance is due to a pH shift from neutral to alkaline caused by the enzyme hydrolysis of urea. The method is also suitable for kinetic studies of deaminase enzyme systems. Webb1 sep. 2024 · Examples of commercial rapid urease tests commonly available in the United States. The CLOtest® and a second generation test, the hp fast test are shown. Both use urea impregnated agar and a pH indicator system.
