| 1 | 2D NOESY | NMR studies of humanin were carried out in H2O/TFE-d3 7:3 solution containing 60 microM NaN3 at 280 and 298 K. The concentration of the sample was 1.7 mM and the pH of the solution was 2.7 (uncorrected for the presence of TFE). | H2O/TFE-d3 7:3 solution containing 60 microM NaN3 | 60 microM sodium azide | 2.7 | ambient | 298 | |
| 2 | 2D TOCSY | NMR studies of humanin were carried out in H2O/TFE-d3 7:3 solution containing 60 microM NaN3 at 280 and 298 K.
