Dna analysis kit for analyzing dna through scanning electron microscopy, dna-protein-polymer complex, composition including the dna- protein-polymer complex, and dna analysis method using the dna-protein- polymer complex

Abstract

Provided are a DNA analysis kit for analyzing DNA through scanning electron microscopy (SEM), a DNA-protein-polymer complex, a composition including the DNA-protein-polymer complex, and a DNA analysis method using the DNA-protein-polymer complex. The DNA-protein-polymer complex includes: a DNA molecule; a DNA-binding protein including a peptide, the peptide having an amino acid sequence capable of binding to the DNA molecule and having at least one functional group in at least one of both terminuses thereof; and a polymer, an anhydride thereof or a salt thereof, capable of binding to the DNA-binding protein by intermolecular electrostatic attraction. The DNA-protein-polymer complex is metal-free and enables high-resolution observation and analysis of DNA molecules having various shapes and lengths at almost real-time speed through SEM.
