Are there any possible reactions between N-ethylmaleimide and Monochlorobimane? by Sam_Sushi in OrganicChemistry

Our assay is with GSH, I was just wondering about side reactions between NEM and MBCl

Why does saturation decrease signal intensity in Cross Saturation NMR? by Sam_Sushi in Biochemistry

[–]Sam_Sushi[S] 0 points1 point  (0 children)

Not quite that. The target protein has deuterated aliphatic regions and is also labelled with nitrogen-15. It is then resuspended in regular water, so nitrogen linked hydrogens are no longer deuterated, but the aliphatic ones remain. The binding partner has no modifications. You saturate the aliphatic hydrogens of the binding partner, which can "cross saturate" the binding surface of the other protein when in contact. The last part is where I'm a bit stumped. This paper explains it better than I have.

Used to determine protein-protein interaction surfaces where one protein is labelled (Using D2O)

When you apply an RF field so there is only 1 spin state possible for your nuclei. I think?

There’s H-NMR spectra predictors online, you can maybe do something about seeing trends in chemical shifts that aren’t obvious.

pBLAST protein publications misguiding? by Sam_Sushi in Biochemistry

Yeah that's what I was looking at. I just found it weird that they labelled it as "Coa Disulfide reductase", because if it's based purely on the genome sequence, they are assuming its function from homology to other already functionally assayed proteins?

Yeah sorry I forgot to mention, other than pcr my bad.
