A comparison of negatively stained electron micrographs and projections obtained from single crystal X-ray studies: the lipovitellin complex from lamprey.
The analysis of single crystals of the lipovitellin complex from lamprey has made it possible to compare electron density projections derived from X-ray diffraction and density modification methods with previously published electron micrographs. The close correlation between the images obtained by the two methods demonstrates that the fidelity of images obtained by electron microscopy is excellent despite the loss of specimen order. These correlations also attest to the ability of density modification methods, currently used in macromolecular crystallography, to estimate the phases of small angle X-ray reflections.
