IS THEIR ANY NMR EXPERMENT ON 700 VNMR TO KNOW THE duterium percentage of randomly deuterated protein WHICH PREPARED USING 90 PERCENT D20 AND 10 PERCENT H2O ?

Assignment strategies for aliphatic protons in the solid-state in randomly protonated proteins
Assignment strategies for aliphatic protons in the solid-state in randomly protonated proteins
Abstract Biological solid-state nuclear magnetic resonance spectroscopy developed rapidly in the past two decades and emerged as an important tool for structural biology. Resonance assignment is an essential prerequisite for structure determination and the characterization of motional properties of a molecule. Experiments, which rely on carbon or nitrogen detection, suffer, however, from low sensitivity. Recently, we introduced the RAP (Reduced Adjoining Protonation) labeling scheme, which...

[Question from NMRWiki Q&A forum] Randomly duterated protein is useful to get noesy experments ?
Randomly duterated protein is useful to get noesy experments ?
Dear NMR WIKIers
I got doubt that can I use Randomly duterated protein (40 to 60 percent ) to get 3D (C13 EDIT and N15 EDIT) noesy experiments ? because if i duteriated the protein randomly the peak intensity drop would be there. but from standard formula NOE = 1/R6.
I am afraid of error from intensity drop .
could you please suggest any reference related to this ?
Thnaking you

High resolution 13C-detected solid-state NMR spectroscopy of a deuterated protein
High resolution 13C-detected solid-state NMR spectroscopy of a deuterated protein
Abstract High resolution 13C-detected solid-state NMR spectra of the deuterated beta-1 immunoglobulin binding domain of the protein G (GB1) have been collected to show that all 15N, 13Cā?², 13CĪ± and 13CĪ² sites are resolved in 13Cā??13C and 15Nā??13C spectra, with significant improvement in T 2 relaxation times and resolution at high magnetic field (750 MHz). The comparison of echo T 2 values between deuterated and protonated GB1 at various spinning rates and under different decoupling schemes indicates...

Iterative algorithm of discrete Fourier transform for processing randomly sampled NMR
Abstract Spectra obtained by application of multidimensional Fourier Transformation (MFT) to sparsely sampled nD NMR signals are usually corrupted due to missing data. In the present paper this phenomenon is investigated on simulations and experiments. An effective iterative algorithm for artifact suppression for sparse on-grid NMR data sets is discussed in detail. It includes automated peak recognition based on statistical methods. The results enable one to study NMR spectra of high dynamic range of peak intensities preserving benefits of random sampling, namely the superior resolution in...

Help!!Why does a deuterated protein behave even more poorly than the protonated one?
A 20kDa protein, about half of the total signals can be observed in CBCA(CO)NH experiment when protonated with sample concentration of 1mM. However, after deuterated, hardly any signals can be observed with the same concentration in this experiment. We use the same pulse sequence except adding deuterium decoupling in the deuterated one. I don't know why? Help!!
