The Biomolecular NMR Core Facility provides support across the Biological Sciences Division at the University of Chicago. A partial list of the research currently actively supported by the facility includes
We also actively develop new methods to assist our users in approaching their scientific problems.
Aliphatic Chain Length by Isotropic Mixing (ALCHIM) is a 1H NMR technique for identifying saturated and unsaturated acyl groups in complex mixtures of lipids by using a selective TOCSY technique. It can distinguish ω-3, ω-6, and ω-9 unsaturated fatty acid and has shown to be effective in samples relevant to food science (coconut oil) and biomedical sciences (neutral fats extracted from mouse adipose tissue). We also demonstrate that it can be used in whole adipocytes indicating that it will have applications in whole tissues. This technique provides researchers to a new tool for probing lipid samples in biomedically relevant samples.
