(a) 600 MHz - HSQC spectrum of 5 mg/mL pHtrII-cyt in buffer D plus 4 M KCl at +10 (red) and +20 (black) recorded in thin high salt tubes. Signals correspond to backbone and side-chain NH or NH2 groups. There is no Trp in the pHtrII-cyt sequence, so there are no resonances expected beyond 10 ppm. (b) Same as in (a) measured in buffer D using the same type of NMR tubes.
