Neomycin improves cationic lipid-mediated transfection of DNA in human cells

Bioorg Med Chem Lett. 2005 Jul 15;15(14):3467-9. doi: 10.1016/j.bmcl.2005.04.038.

Abstract

Delivery of oligonucleotides has been a major impediment in the development of nucleic acid based drugs. In this report, we show that neomycin, an aminoglycoside antibiotic, when combined with a cationic lipid preparation such as DOTAP, enhances transfection efficiency of both reporter plasmids and oligonucleotides and results in a significant increase in transgene expression. The results described here open a new lead in ongoing efforts for oligonucleotide delivery.
