Abstract
A method for determination of activity of a cholesterol oxidase comprises the following steps. A monomolecule film comprising a sterol and a phospholipid is formed on a surface of a cholesterol oxidase solution. Subsequently, a surface pressure of the monomolecule film is measured in order to find a rate of increase in the surface pressure of the monomolecule film where a magnitude of the activity of the cholesterol oxidase is defined by the rate of increase in the surface pressure.
