[Question from NMRWiki Q&A forum] How to adjust the receiver gain in a deuterium oxide protein sample?
How to adjust the receiver gain in a deuterium oxide protein sample?
I am running a 15N HSQC on a protein sample which is in a 100% deuterium oxide solvent. The command rga in TopSpin gives a value of >10000 for the receiver gain. I understand this is happening because there is no water signal and hence the receiver gain is optimizing the S/N. However, should the experiment be run with that high value or should it be adjusted to a value of a size similar to the one used on water samples?

1H NMR spectra of the CuA center of N2OR from Pseudomonas stutzeri, and a mutant enzyme that contains only CuA, were recorded in both H2O- and D2O-buffered solution at pH 7.5. Several sharp, well-resolved hyperfine-shifted 1H NMR signals were observed in the 60 to...
