About 14% of the entries in the [[Protein Data Bank]] were determined by nuclear magnetic resonance in solution (NMR) as of mid-2008. 85% were determined by X-ray crystallography, and <1% by other methods. NMR can only be used for relatively small macromolecules (see | About 14% of the entries in the [[Protein Data Bank]] were determined by nuclear magnetic resonance in solution (NMR) as of mid-2008. 85% were determined by X-ray crystallography, and <1% by other methods.
