This is addressed to those of you who work on N15/C13 labelled proteins.
The folks I work with, that is, the Purdue Interdepartmental NMR Facility,
are interested in purchasing a N15/C13 protein to use as a standard for the
usual suite of protein structure experiments.
I know that Cambrige Isotopes offers a N15/C13 labelled Ubiquitin, but since
I am not very expert in this area labelled protein NMR, I thought that I
should ask as whether there are other, perhaps better, products on the
market.
Also, does anyone sell a N15/C13 labelled protein prepared as a NMR
standard, that is, in a buffer solution in a sealed NMR tube?
Thank you for your help. I am certain that I will be having more questions
for you soon.
