COMPOSITION COMPRISING DNA BINDING PEPTIDE FOR DNA STAINING

摘要

The present invention relates to a composition for DNA staining, which can be safely used for researchers, can prevent DNA photocleavage, and can be applied to various fields. According to the present invention, when DNA is stained by using a fluorescent protein and a particular peptide bound to DNA, such a fluorescent protein-peptide is safe to researchers, suppresses DNA photocleavage, and allows reversible staining, thereby enabling efficient DNA staining. Therefore, the composition for DNA staining of the present invention can be variously used in DNA-related research.
