Simultaneous measurement of ionic current and fluorescence from single protein pores.
The ability to simultaneously monitor both the ionic current and fluorescence from membrane channels and pores has the potential to link structural changes with function in such proteins. We present a new method for simultaneously measuring single-channel electrical currents and fluorescence from membrane proteins by using water-in-oil droplet bilayers. We demonstrate the simultaneous fluorescence and electrical detection of stochastic blocking by cyclodextrin in multiple staphylococcal alpha...Expand abstract
