  • Method for simultaneously measuring activity of various enzymes by using multi-wavelength absorption single channel
    Patent number: 9611502
    Abstract: A method for simultaneously measuring the activities of multiple kinds of enzymes in single channel through concimitantly monitoring multiple wavelength absorbances is claimed; based on linear additivity of absorbances and the isoabsorbance wavelengths of chromogenic substrates and their chromogenic products, both the principles for the combination of chromogenic substrates required for simultaneously measuring the activities of multiple kinds of enzymes in single channel through concimitantly monitoring multiple wavelength absorbances and an approach for data processing to eliminate the interference of the overlapped absorbances are developed, kinetic analysis of reaction curves via numerical integration eliminates the interference of all substrates and products and estimates the maximal reaction rates of the enzymes to be measured, giving the linear ranges and the limits of quantification for simultaneously measuring the activities of multiple kinds of enzymes in single channel comparable to those by separa
