A simple fluorometric assay for DNA exonuclease activity based on graphene oxide
1Department of Chemistry, Seoul National University, Gwanak-ro, Gwanak-gu, Seoul 151-747, Republic of Korea.
Abstract:
A new assay platform for DNA exonuclease activity is developed based on the preferential binding of single-stranded DNA (ssDNA) over double-stranded DNA (dsDNA) to graphene oxide. This approach allows a simple and quantitative activity measurement in a short time at low cost.
