In-vitro dissolution dynamic nuclear polarization for sensitivity enhancement of NMR with biological molecules

Abstract

Dissolution dynamic nuclear polarization (D-DNP) is a technique to prepare hyperpolarized nuclear spin states, yielding a signal enhancement of several orders of magnitude for liquid-state NMR. Here, we describe experimental procedures for the application of D-DNP in high-resolution NMR of biochemical compounds, to determine the time evolution of biochemical processes and intermolecular interactions.
