The activities of a first and second reporter enzyme are quantified by measuring the light signal produced by degradation of a first substrate by the first reporter enzyme and the light signal produced by the degradation of a second substrate by a second reporter enzyme. Both quantifications are sequentially performed on the same aliquot of sample extract.
