SSM technique. A schematic diagram of a proteoliposome containing SERCA and PLN adsorbed to a SSM and subjected to an ATP concentration jump is shown. If the ATP jump induces net charge displacement across the protein, a current transient is measured (the red circles are electrons) when the potential difference applied across the whole system is kept constant.
