Web13C NMR Spectroscopy. Wild-type and mutant Co-LuxS was dialyzed against a buffer containing 50 mM NaH2PO4- Na2HPO4 (pH 7.0) and 50 mM NaCl at 4 °C for 22 h with four changes of the buffer and concentrated in an Amicon apparatus (Millipore) to ~5 mM. The LuxS reaction was initiated by mixing Co-LuxS (typically 2 mM) and an Web13C CP/MAS NMR techniques have been used to evaluate the structure of four hyper-cross-linked polystyrene resins. Single-pulse excitation (SPE) 13C spectra have allowed the …
