19F NMR spectroscopy is a powerful probe of protein conformation and dynamics but is intrinsically limited by low sensitivity common to other NMR techniques. Here, we integrate photochemically induced dynamic nuclear polarization (photo-CIDNP) with genetically encoded 19F labels to enhance sensitivity by up to 220-fold...

It is found that G4 structural stability, interactions, and NMR signal detectability are cell-type-dependent, and it is demonstrated that cell lysates can serve as a practical platform for reflecting G4 stability in intact cells.

A neural network is proposed, the Spin Echo to Pure Shift Network (SE2PSNet), that generates high-quality pure shift spectra with accurate integrals, resolving overlapping signals while preserving the sensitivity and accurate integral information, with broad potential applications.
