Chemiluminescent assay for the determination of density of activity of viable cells

摘要

A chemiluminescent assay for the determination of density or activity of viable cells which comprises incubating viable cells in the presence of a quinone whose reduced form redcues dissolved oxygen resulting in formation of hydrogen peroxide, reacting the hydrogen peroxide with a chemiluminescence reagent in the presence of a fluorescent substance to cause fluorescence and determining density or activity of the cells on the basis of the intensity of fluorescence.
