The growth of ordered two‐dimensional sheets of 70 S ribosomes from Bacillus stearothermophilus

Abstract
Well ordered two‐dimensional sheets of intact 70 S ribosomes from Bacillus stearothermophilus have been obtained in vitro using salt‐alcohol mixtures. These sheets consist of relatively small unit cells with dimensions of 200 ± 20 Å and 400 ± 30 Å. Diffraction patterns of electron micrographs of these sheets stained with uranyl acetate contain features to 42 Å resolution.
