11 October 1993 Electroporation visualized under a multishot pulsed laser fluorescence microscope system

We describe a new fluorescence microscope system, which is the third generation of our pulsed-laser microscope systems developed for the purpose of capturing rapid cellular phenomena. Time resolution of this latest version is supported by the combination of a Q- switched Nd:YAG laser producing a burst of 4 pulses and a large format framing camera. We obtain series images at intervals on the order of 10 microsecond(s) with exposure times of 30 ns. With this multi-shot pulsed laser fluorescence microscope system, we examined the behavior of the transmembrane potential in a sea urchin egg under an intense electric field. Irreversible process of cell electroporation was revealed in serial images taken under a single electric pulse of microsecond duration.
