The University of Pennsylvania has a large number of scientific and clinical faculty who are interested and experienced in the application of NMR to in vivo biochemical and physiological studies. However, there is a serious lack of NMR instrumentation for in vivo metabolic studies on animals. The instrument requested in the present proposal will solve this problem. The proposal requests funds for the purchase of a 2.3T, 30 cm in vivo animal NMR spectrometer for a large group of NIH-supported users.
