title: Crystallization of bacteriophage MS2.
abstract: Crystals of bacteriophage MS2 have been obtained by slowly cooling a 1% virus solution from 23 degrees C to 0 degrees C in the presence of poly(ethylene glycol) 6000. The crystals were colorless, needle-like, anisotropic and very fragile. Electron microscopic observation of the crystals revealed a two-dimensional lattice of particles with RNA phage morphology and dimensions. Preliminary X-ray examination of the crystals confirmed their viral nature.
