DNA-mediated supercharged fluorescent protein/graphene oxide interaction for label-free fluorescence assay of base excision repair enzyme activity

Abstract

The interaction between supercharged green fluorescent protein (ScGFP) and graphene oxide (GO) as well as the resulting quenching effect of GO on ScGFP were investigated. Based on this unique quenching effect and the DNA-mediated ScGFP/GO interaction, a label-free fluorescence method has been established for homogeneously assaying the activity and inhibition of base excision repair enzyme.
