Abstract (en)
[origin: DE19726186A1] The invention relates to complexes consisting of nucleic acid and polyethylene imine (PEI) in which the PEI is modified by means of hydrophilic polymers, such as polyethylene glycol, linked to the PEI by a covalent bond, and to a method for producing said complexes. A cellular ligand such as transferring is possibly bound to the PEI. The complexes can be used for producing pharmaceutical compounds for the transfer of therapeutically active genes in mammalian cells.
