title: A novel method for transfer of two-dimensional crystals from the air/water interface to specimen grids. EM sample preparation/lipid-layer crystallization.
abstract: Transfer of two-dimensional (2-D) crystals formed on lipid layers by suspension from a wire loop is described. This method gives better recovery and better preservation of 2-D crystals than attained in the past. The method has been applied to crystals of yeast RNA polymerase II to enable their analysis in the frozen hydrated state.
