4388166 Electrochemical measuring apparatus provided with an enzyme electrode
PATENT ABSTRACTS
may also include beta lactamase enzyme detection utilizing the reaction of the same reagent system carrying the specimen with a penicillin substrate.
343
Synthetic substrates are provided which may be represented as A-D. The A moiety thereof includes an amino acid, polypeptide, or derivative thereof. The D moiety thereof includes 7-amino coumarin derivatives having an electron withdrawing substituent group at the 3 position carbon or fund between the 3 and 4 position carbons.
4389485 URICASE PRODUCTION METHOD Robert Olivieri, Eugeni Fascetti, Pierluig Ciuffolotti, Ludwig Degen, Mentana, Italy assigned to E N I Ente Nazionale Idrocarburi it has been found that highly active uricasc can be produced by fermentation from the microorganism Micrococcus roseus NRRL B 12196. The optimum activity of this microorganism is close to the pH values of the physiological liquors. The uricase so produced can be exploited in the clinical diagnostics for determining uric acid.
