The H3B Membrane Neutron SpectrometerThe H3B spectrometer is designed for the study of partially ordered systems, such as stacked biological membranes and model membranes. A typical sample consists of a lipid-water multilayer, which may contain reconstituted integral membrane proteins, drugs, cholesterol, or other molecules whose location inside the membrane is to be determined. Selective deuteration of the membrane components and H2O-D2O exchange is applied in elucidating the structure. The spectrometer and associated equipment are controlled by a VAX 4000-400, and various types of sample holders are available. Software packages have been developed to assist the users in data analyses and the determination of scattering density profiles accross membranes. |
