High Resolution 1H NMR Metabolomics Using Slow and Fast Magic Angle Spinning
EMSL Project ID
42296
Abstract
We propose to develop both slow and fast magic angle sample spinning NMR methods that is capable of high resolution and high sensitivity metabolic profiling on biological samples, in particular tissue samples, with volume as small as 300 nanoliters (nL) to sample volume as large as a few milliliters. The nL capability will make it possible to follow the metabolic changes through a continued investigation on a single small laboratory animal, and ultimately on a patient, over a long period of time using minimally invasive tissue biopsy and biofluid samples. The large sample size will allow a variety of biological systems with different size to be investigated. These NMR metabolic profiling methods, including the standard solution NMR metabolomics, will be/are being extensively used by us for the studying of disease progression in obesity, atherosclerosis (i.e., the fat accumulation in the part of the artery that is directly linked to the heart), and the impact of low dose radiation to the metabolic profile using mouse models.
