Homonuclear Mixing Sequences for Perdeuterated Proteins
Homonuclear Mixing Sequences for Perdeuterated Proteins
Publication year: 2010
Source: Journal of Magnetic Resonance, In Press, Accepted Manuscript, Available online 26 October 2010</br>
Kuo-Ying, Huang , Ansgar B., Siemer , Ann E., McDermott</br>
We test the performance of several 13C homonuclear mixing sequences on perdeuterated microcrystalline ubiquitin. All sequences were applied without 1H decoupling and at relatively low MAS frequencies. We found that RFDR gave the highest overall transfer efficiency and that DREAM performs surprisingly well under these conditions being twice...

[Question from NMRWiki Q&A forum] How do you port pulse sequences to different field strength?
How do you port pulse sequences to different field strength?
Hi, when you set up a pulse sequence at a different magnet field strength - starting with an existing set of parameters - what do you look at?
Does length of shaped pulses always need to be changed?
What pulse lenghts need to be adjusted?
When it is necessary to re-build RF waveforms - for what kinds of pulses?

[Question from NMRWiki Q&A forum] 2D pulse sequences for NMR of protein/peptide complexes?
2D pulse sequences for NMR of protein/peptide complexes?
Hello, I am looking for some 15N/13C-filtered 2D NOESY and 2D TOCSY pulse sequences to run on a Varian 600. Does anyone have any ideas where I would get some tried and tested pulse sequence input files?
Check if somebody has answered this question on NMRWiki QA forum

[NMR software blog] Universal Hole
Universal Hole
Earlier in this week I cited a paper by Kobzar and Luy. It contains the statement:
The coupling extraction procedure is not yet implemented in any available software.
that confirms and enforces what I have always being saying:
Any NMR program contains some hole and by the time it's filled another hole appears.
What they have found is a kind of super-hole that is common to every program. My first thought would normally be: "If nobody cares, why should I?", but this time I was intrigued by a figure just above the cited statement. That figure resembles a picture of mine I...
