Quizplus · Accepted Answer

Nuclear magnetic resonance (NMR) is limited to proteins with a molecular mass of 50 kD or less. This is because larger proteins tend to have too many atoms to provide clear signals in the NMR spectrum. X-ray crystallography, fingerprinting, and mass spectroscopy are not limited by molecular mass and can be used to study proteins of any size.
