title: Localized Patch Clamping of Plasma Membrane of a Polarized Plant Cell : Laser Microsurgery of the Fucus spiralis Rhizoid Cell Wall.
abstract: We used an ultraviolet laser to rupture a small region of cell wall of a polarized Fucus spiralis rhizoid cell and gained localized access to the plasma membrane at the growing apex. Careful control of cell turgor enabled a small portion of plasma membrane-bound cytoplasm to be exposed. Gigaohm seals allowing single-channel recordings were obtained with a high success rate using this method with conventional patch clamp techniques.
