PROTEIN TRANSDUCTION DOMAIN BASED ON GOLD NANOPARTICLE-APTAMER CONJUGATE AND METHOD FOR PRODUCING SAME

摘要

The present invention relates to a protein transduction domain comprising gold nanoparticles and aptamers binding to the surfaces of the gold nanoparticles. The protein transduction domain according to the present invention is expected to be useful for diagnosing or treating diseases since the protein transduction domain specifically binds to proteins, which are to be delivered by various tagged aptamers or protein-specific aptamers binding to gold nanoparticles, thereby effectively delivering the proteins into cells, can be harmless to humans by using gold nanoparticles having very little cytotoxicity, and allows easy confirmation of the intercellular position thereof by reflecting lights of various wavelengths.
