Highly purified preparations of empty and full capsids were generated by subjecting purified adenovirus preparations to repeated cesium chloride gradient separations. PAGE results revealed that empty capsids contain at least five bands that correspond to proteins absent from the mature virus proteome.

The cesium chloride precipitated the DNA out of solution so that it could be isolated, purified, and characterized. The cesium chloride broke the DNA at specific sequences, creating fragments of varying sizes. The cesium chloride provided a medium of variable density, so that DNA of different density would aggregate in specific regions.

The caesium chloride structure is composed of a primitive cubic lattice with a two atom basis, where both atoms have eight-fold coordination. The chloride atoms lie upon the lattice points at the edges of the cube, while the caesium atoms lie in the holes in the center of the cubes. This structure is shared with CsBr and CsI and many ...
