摘要:
The invention relates to a novel circuit arrangement for electrotransfection or electrofusion, which enables the transportation of DNA and/or other biologically active molecules to the nucleus of higher eukaryotic cells or the fusion of cells, independent of cell division and with reduced cell mortality.
摘要:
The invention relates to a buffer solution for suspending animal or human cells and for dissolving biologically active molecules in order to introduce biologically active molecules into cells using an electric current. The inventive buffer solution has a buffering capacity of at least 20 mmol−1×pH−1 and an ionic strength of at least 200 mmol×1−1 during a change to the pH value from pH 7 to pH 8 and at a temperature of 25° C. The use of a buffer solution of this type allows biologically active molecules to be introduced into animal and human cells with a high degree of transfection efficiency and at the same time a low cell mortality. Different cell types, in particular dormant and actively dividing cells of low activity, can be successfully transfected in the buffer solution.
