Abstract
1517146 Detection of urea BOEHRINGER MANNHEIM GmbH 22 March 1977 [25 March 1976] 11994/77 Heading G1B [Also in Division C3] A reagent for the detection of urea comprises a stabilized urease which contains, as stabilizing agent, a mixture of glutathione, ethylenediamine tetraacetic acid and citrate, and a system for the detection of ammonia. The preparation of a test film for the detection of urea in blood or serum is described, the said film comprising a polyvinyl chloride film coated with an acid mixture containing the said stabilized urease, bromothymol blue, disodium hydrogen phosphate, polyvinyl acetate dispersion, sodium alginate solution and dioctyl sodium sulphosuccinate.
