A new method for calibrating micropipets and determining accurate injection volumes using a pressure-based injector has been developed. This method employs the bioluminescent protein aequorin and can be used to determine injection volumes as small as 3 pL. The calibration plots are linear over at least 3 orders of magnitude. In contrast to conventional micropipet calibration methods that employ fluorescent molecules, the present method produces small background signals.
