Chem Commun (Camb). 2012 Apr 4;48(27):3339-41. doi: 10.1039/c2cc00027j. Epub 2012 Feb 24.

Abstract

A pair of isotope-coded, fluorous photoaffinity labeling reagents has been developed and coupled with a peptide. The modified peptides form adducts with methanol upon light illumination, which show characteristic isotope labeling patterns in mass spectra and can be separated from other peptides through fluorous silica.
