ABSTRACT:
A buffer solution for suspending animal or human cells and for dissolving biologically active molecules in order to introduce the biologically active molecules into the cells using electric current. The buffer solution includes at least one of sodium succinate, mannitol and sodium lactobionate. The buffer solution has a buffer capacity of at least 20 mmol*l−1*pH−1at a change in the from pH 7 to pH 8 and at a temperature of 25° C., and an ionic strength of at least 200 mmol * l−1.
