  • Process and reagent for the kinetic determination of enzyme substrates
    Patent number: 4229527
    Abstract: Kinetic determination of enzyme substrates by means of coupled reactions comprising selecting the reaction parameters so that the most specific part reaction of a reaction sequence becomes rate-determining for the whole reaction sequence wherein the rate-determining part reaction follows first or pseudo-first order kinetics.
    Type: Grant
    Filed: October 23, 1978
    Date of Patent: October 21, 1980
    Assignee: Boehringer Mannheim GmbH

  • Reagent and method for the determination of cholesterol
    Patent number: 4212938
    Abstract: Cholesterol is determined by incubating a sample suspected of containing cholesterol in an aqueous medium with cholesterol oxidase and determining either the oxygen consumption, the hydrogen peroxide formed, or cholestenone, as a measure of the initial cholesterol content; reagent compositions comprising cholesterol oxidase and a system for the determination of H.sub.2 O.sub.2 or for the determination of cholestenone are provided.
    Type: Grant
    Filed: May 15, 1973
    Date of Patent: July 15, 1980

  • Cholesteroloxidase and method for its production from microorganisms
    Patent number: 4144129
    Abstract: A new enzyme, cholesteroloxidase, is prepared by recovering same from microorganisms, preferably by washing a cholesterol-converting microorganism with butanol/water, disintegrating the microorganism culture and extracting same with a buffer solution containing a non-ionic surface-active agent, and isolating cholesterol oxidase from the extract.
