The amorphous and crystal phases in supersaturated lysosome solutions. In situ TEM images of (A) numerous amorphous solid particles (ASPs); (B) an elongated orthorhombic lysozyme crystal; and (C) a tetragonal lysozyme crystal. The corresponding electron diffraction patterns are shown in D–F, respectively. The arrows in B and C indicate the <001> direction. In C, the (110) face of the tetragonal lysozyme crystal faces upward. [Scale bars: 500 nm (A), 1 μm (B), and 200 nm (C).] In E and F, the crystal zone axes are [10314] and [1 –1 0], respectively.
