Solid State MAS NMR chemical shift assignment of KR2 in DMPC/DMPA proteoliposomes

separate tube (no insert) similar to the experimental sample tube

External referencing via 1-13C chemical shift of Alanine, which is 179.85 ppm with respect to DSS referencing.
15N chemical shifts indirectly referenced from 13C chemical shifts.
