Two-dimensional SLF spectrum of uniformly 15N labeled Pf1 coat protein in DMPC:Triton X-100 bilayers obtained at 700 MHz with the SAMPI4 pulse sequence13. It resulted from signal averaging 64 transients for each of 128 t1 points, and 1024 points were acquired in the direct dimension. The final data matrix had 1024 by 1024 points.
