TWO-DIMENSIONAL 13C–1H HETCOR SPECTRAL ANALYSIS AND STRUCTURAL CHARACTERIZATION OF POLYPEPTIDES BLENDS It is very important to obtain more detailed information about the relationship between the character and miscibility of polypeptide blends. For example, the PG/PLV (50/50) blend sample, the preferred conformation of the PLV is he b-sheet which exists in the PG/PLV (50/50) blend sample. On the other hand, the 31-helix form of PG in PG/PLV blends is almost transformed to the b-sheet form in the PG/PLV blend sample.

Modern NMR spectrometers enable rapid coherent switching of both frequency and phase of the RF during a pulse, and the FSLG sequence is relatively straightforward to implement. Since the only parameters that need to be adjusted are the offset frequency ÁLG and the duration of the successive frequency intervals , the sequence is robust and can easily be readjusted if necessary. Mixing is achieved with a simple Hartmann-Hahn contact, in order to select for correlations via strong heteronuclear dipolar couplings and to avoid cross peaks due to spin diffusion in the proton reservoir.
