Neutron scattering-length density (NSLD) variation as a function of D2O concentration in the aqueous phase. (a) The NSLDs of unlabeled biomolecules are such that significantly distinct contrast-match points exist for lipids, proteins and nucleic acids. (b) Uniform partial or total deuterium labeling of a protein increases the NSLD and allows selective matching of individual proteins with differing degrees of deuterium substitution. |
