| 摘要 |
Novel peptides derived from antibody complementarity determining regions (CDRs) that enhance delivery of macromolecules into cells, particularly when used in combination with cationic lipids, are provided. The peptides can be combined with cationic lipids, and compositions of cationic lipids associated with enhancer elements, to provide reagents that can complex with macromolecules such as nucleic acids, proteins and peptides and permit introduction of these macromolecules into a variety of cells and tissues in vitro or in vivo with greatly enhanced efficiency compared to other lipid-based reagents. Methods for delivering macromolecules into target cells and tissues using the lipids and enhancer elements are provided.
