[Question from NMRWiki Q&A forum] Best pulse sequence for HSQC in Guanidine-HCl
Best pulse sequence for HSQC in Guanidine-HCl
Hello,
I would like to acquire a series of HSQC spectra of an 15N-labeled 12 kDa protein unfolding (over the course of hours) in 3M GuaHCl. I have access to a Varian 600 spectrometer with a conventional probe. Due to the high ionic strength of the sample, tuning and shimming is a little difficult. However, I can record a sort-of-decent HSQC using a WaterGate gradient enhanced WGgNhsqc sequence. I am limited to using a protein concentration of about 250 uM. I've determined the pw90 to be 12.125 at a tpwr of 63.
Using WGgNhsqc, the protein...
