Abstract

1,192,046. Determination of urea. CALBIOCHEM. 28 June, 1967 [30 June, 1966], No. 29939/67. Heading B1X. A solid assay material for dissolving in water to provide a reagent for determining urea comprises alpha-ketoglutaric acid, urease, glutamic dehydrogenase, reduced diphosphopyridine nucleotide (DPNH), adenosine diphosphtate or its water soluble salt, a stabilizer and at least one buffer chosen from sodium or potassium phosphate, carbonate or bicarbonate, tris (hydroxymethyl) amino-methane, glycine. The stabilizer may be a sulfydryl compound, for example dithioerythritol, cysteine or glutathione, or sodium potassium tartrate, sodium sulphate, sodium tartrate, potassium sulphate or sodium glutamate. The assay material may include a bulking agent, for example mannitol or a polyhydric polymer. The enzymes in the form of pre-assayed; stabilized dry powders are mixed with the other components, and the product packed into single test capsules. The reactions used urease in the test are urea + water # 2NH 4 <SP>+</SP> + HCO 3 -DPNH + NH 4 <SP>+</SP> + alphaketoglutarate glutamate dehydrogenase # glutamate + DPN. The amount of DPNH converted to DPN is measured.
