  • Hydrolysis of protein-bound cholesterol esters
    Patent number: 4275152
    Abstract: A novel process is described for hydrolyzing protein-bound cholesterol esters such as are found in blood serum. The method comprises contacting sample containing protein-bound cholesterol esters with a compatible mixture of an enzyme preparation which demonstrates cholesterol ester hydrolase activity and, as an effector, a surfactant which is an alkyl phenoxy polyethoxy ethanol comprising a polyoxyethylene chain of less than about 20 oxyethylene units.Hydrolysis compositions comprising compatible mixtures of an enzyme preparation which demonstrates cholesterol ester hydrolase activity and an effector which is a surfactant as described are also disclosed, as are analytical elements comprising at least one layer which includes such a hydrolysis composition.
    Type: Grant
    Filed: July 30, 1979
    Date of Patent: June 23, 1981
    Assignee: Eastman Kodak Company
    Inventors: Theodore W. Esders, Charles T. Goodhue, Christine A. Michrina

  • Hydrolysis of protein-bound triglycerides
    Patent number: 4179334
    Abstract: A novel process is described for hydrolyzing protein-bound triglycerides such as blood serum triglycerides comprising contacting sample containing protein-bound triglycerides with a compatible mixture of an enzyme preparation which demonstrates triglyceride hydrolase activity and, as an effector, a surfactant.Hydrolysis compositions comprising compatible mixtures of an enzyme preparation which demonstrates triglyceride hydrolase activity and an effector which is a surfactant are also described, as are analytical elements comprising at least one layer which includes a hydrolysis composition which comprises such a compatible mixture of an enzyme preparation which demonstrates triglyceride hydrolase activity and a surfactant.
