Abstract: A method for the production of a biomolecular complex having at least two functional elements each attached to a target molecule or area through binding elements, wherein each functional element is attached to a specific binding element, the binding element being a nucleotide sequence and the target molecule or area comprising the corresponding target sequence, and the target molecules or areas being separated from each other by a first linker or spacer and an optional second linker, the linkers being nucleic acid polymers having a pre-determined physical property.

Abstract: A synthetic transport entity is used for transferring a nucleic acid sequence of interest across a biological membrane. The transport entity comprises a functional element (FE), which increases the efficiency of transfection (e.g. polyethylene glycol (PEG) or a nuclear localisation signal), a binding element (BE), such as a peptide nucleic acid (PNA), and a carrier molecule comprising the nucleic acid of interest and a BE target sequence. The transport entity can be altered in a controlled manner at the surface of the membrane or after having passed across the membrane or having been taken up by the cell, and comprises at least one alteration site that, when altered, changes a property of the transport entity.

Abstract: The present invention concerns biomolecular complexes and in particular a method for linking biomolecules in sets of two or more, with predefined three-dimensional orientation and spacing between the two or more biomolecules. The linking method has application in the construction of novel, highly specific vehicles for drug delivery, e g in gene therapy, and in the construction and performing of assays for the study of biomolecular interaction, e g receptor-ligand interaction studies.

Abstract: The present invention relates to a method of introducing organic molecules carrying genetic information into isolated target cells, which comprises the step of passing a supernatant comprising said organic molecules through a fluidized collection of said target cells during an essentially constant flow. The fluidisation is provided by directing a flow of the supernatant so as to essentially counteract the gravitational force of the target cells, or alternatively a force applied thereon. Thus, the present method enables an efficient introduction of genetic information into the target cells.

Abstract: The present invention relates to a novel method of genetic modification, wherein a nucleic acid of interest is transferred across a biological membrane, and/or directed to a specific location within or on a cell, by use of a synthetic transport entity. The transport entity according to the invention is new as such and produced by coupling a functional element (FE), such as a nuclear localization signal (NLS), an antennapedia peptide of a protein comprising both membrane translocation and nuclear transport properties, to a binding element (BE), such as a peptide nucleic acid (PNA), preferably separated by a linker molecule, which combination is then hybridized to a BE target sequence present on a carrier, which also includes the nucleic acid of interest. The present nucleic acid of interest may for example be a gene encoding a peptide, a protein or an RNA, or any other nucleic acid useful in genetic recombination events.
