Abstract
Compositions and methods for enhancing delivery of molecules, e.g. biological agents, into cells are described. The composition is a conjugate of the biological agent, preferably a nucleic acid analog having a substantially uncharged backbone, covalently linked to a peptide transporter moiety as described. Conjugation of the peptide transporter to a substantially uncharged nucleic acid analog, such as a morpholino oligomer, is also shown to enhance binding of the oligomer to its target sequence and enhance antisense activity.
