Figure 4. HN region of the ¹H NMR spectra of 1 mM SP-B (1–25,63–78) in SDS micelles at 45°C (red) and 1.5 mM SP-B (8–25,63–78) in SDS micelles at 37°C (blue).

The number of transients was 32. The intensity scale is arbitrary but has been normalized to take into account the differences in peptide concentration.
