Besides the historical and traditional use of nuclear magnetic resonance (NMR) spectroscopy as a structure elucidation tool for proteins and metabolites, its quantification ability allows the determination of metabolite amounts and therefore enzymatic activity measurements. For this purpose, ¹H-NMR with adapted water pulse pre-saturation sequences and calibration curves with commercial standard solutions can be used to quantify the photorespiratory cycle intermediates, 2-phosphoglycolate and...

Enzyme responsive LipoCEST agents: assessment of MMP-2 activity by measuring the intra-liposomal water 1H-NMR resonance shift
Mobile proton containing solutes can be detected by MRI via Chemical Exchange Saturation Transfer(CEST)method. The CEST sensitivity is dramatically enhanced by using, as exchanging protons, the water molecules confined inside liposomes, properly shifted by a paramagnetic Shift Reagent. The chemical shift of the intraliposomal water resonance(?IL) is affected by the overall shape of the supramolecular system. Herein, it is shown that ?IL of a spherical LipoCEST...
