    摘要: The resent invention relates to a method of characterizing the biological activity of a sample, the method comprising: (a) expressing a DNA sequence in a cell, wherein the DNA sequence encodes a protein or polypeptide selected from the group consisting of (i) a green fluorescent protein having a protein kinase recognition site, or (ii) a green fluorescent protein wherein one or more amino acids have been substituted, inserted or deleted to provide a binding domain of a second messenger, or (iii) a hybrid polypeptide of green fluorescent protein (GFP) or a modified GFP and a binding domain of a second messenger or an enzyme recognition site; and (b) measuring the fluorescence of said GFP in said cell in the absence and presence of a test sample; and (c) comparing the GFP fluorescence measured in step (b); wherein a difference between the fluorescence measured in the absence and presence of said sample is indicative of the biological activity of said test sample.
