Bispyridines improve the labeling of nucleophiles, including amines and thiols and are particularly useful for improving labeling with acidic and basic labels. Use of bispyridines with such labels dramatically increases labeling compared to protocols without a bispyridine. The labeled nucleophile can then be subjected to standard analytical methods.

The presence of mild electrophiles, such as aldehydes, during the denaturation of glycoproteins or glycopeptides and subsequent enzymatic deglycosylation reduces artifacts in subsequent analyses of the glycans released from the glycoproteins or glycopeptides.
