(a) Structure of ζ-SAIL Tyr and the magnetization pathway related to the assignment of the 13Cζ atom. (b) Carbon spectra of EPPIb selectively labeled by ζ-SAIL Tyr in 100% H2O, 50% H2O/50% D2O, and 100% D2O solutions. These spectra were acquired using a Bruker DRX600 spectrometer equipped with a TCI cryogenic probe at 40 °C (Reproduced from Takeda et al. [45] with permission)
