Electroporation is typically used to transfer DNA into cells by increasing the permeability of cell membranes. The groups of Stefano Maffini and Andrea Musacchio now found a way to make electroporation accessible for the delivery of single polypeptides and multi-subunit protein assemblies to cells.   This very promising method is well-suited to deliver synthetic and chemically modified versions of functional proteins and, therefore, constitutes a promising tool for applications not only in cell biology, but also in chemical and synthetic biology.
