I am attempting to run some filtered NOESY and TOCSY experiments using sequences in the Varian Biopack - CNfiltocsy and CNfilnoesy. The experiments seem to run fine, but when overlaying the processed spectra something seems odd - the TOCSY crosspeaks are not present in the NOESY spectra and vice-versa. Does anyone know why this might be the case?

[Question from NMRWiki Q&A forum] Isotope Filtered NOESY
Isotope Filtered NOESY
I'm an NMR newbie. I know isotope filtering can be used to study a complex under slow exchange, but for fast-exchange, is it possible to acquire only the intramolecular NOEs of the receptor as opposed to intermolecular NOEs between the receptor and ligand? I just want the contacts in the receptor. Thanks.

[Question from NMRWiki Q&A forum] Varian Biopack pulse sequences for intermolecular NOEs
Varian Biopack pulse sequences for intermolecular NOEs
Hi All, I'm trying to set up some experiments to determine intermolecular NOEs in a peptide:protein complex. At the moment from looking at the Biopack library, I have found 4 pulse sequences which will do this and each provide different information (gnoesyNhsqc_CN, gnoesyNhsqc_NN, gnoesyChsqc_CC and gnoesyChsqc_NC). Would people recommend using a combination of all four of these experiments to determine the intermolecular NOEs for use in structure calculations?
