Beschreibung
Zusammenfassung:	The present invention provides a process for the determination of beta -lactamases by the use of 7-cyanoacetylaminocephalosporanic acid and measurement of the colored material thereby formed, wherein ammonium ions are added to the material to be tested, together with phosphate ions and/or an agent splitting off oxygen. The present invention also provides a reagent for the determination of beta -lactamases based upon 7-cyanoacetylaminocephalosporanic acid, which reagent additionally contains ammonium ions, together with phosphate ions and/or an agent splitting off oxygen.
