ABSTRACT:
The invention relates to a method for the transfer of molecular substances, for example proteins or nucleic acids in cells, in the case of using DNA combined with a possible gene expression. A prokaryotic nucleic acid-binding protein is used for the transfer, which is preferably obtained from a thermostable organism. Where the substance to be transferred is a nucleic acid, the protein forms a reversible complex with the nucleic acid. The prokaryotic protein condenses and compacts the nucleic acids. Said nucleic acids can be taken up in the target cells after suitable incubation.
