Splittings, Δ ν, and corresponding order parameters, S_CD, for the resolved peaks of the 2H NMR spectra of POPC-d₃₁/POPG (7∶3) (Figure 1) in the absence and presence of SP-B (1–25,63–78) (Super Mini-B).

The splittings quoted derive from a single experiment; however the uncertainty has been estimated based on the standard deviation in splittings derived from 5 separate control experiments with the same lipid composition.
