Abstract: A method for transfecting a eukaryotic cell in which: a composition that includes at least one saccharide and at least one protein and optionally a salt and/or a pH-stabilizing component is contacted with a nucleic acid and a transfection reagent; a complex of nucleic acid and transfection reagent is formed by interaction with the composition; the complex is dried; the dried complex is stored for a period of time; after storing, the dried complex is taken up into a liquid; and the complex taken up into the liquid is transfected into the eukaryotic cell.

Abstract: The present invention relates to a method for transfecting a eukaryotic cell, wherein a compound comprising at least one saccharide and at least one protein and optionally a salt and/or a component stabilizing pH is brought into contact with a nucleic acid and a transfection reagent, a complex of nucleic acid and transfection reagent is formed by means of interacting with the composition, and the complex is transfected into a eukaryotic cell.
