Redox-neutral, metal-free tryptophan labeling of polypeptides in hexafluoroisopropanol (HFIP)
RSC Chemical Biology.
This work translated the preceding metal-catalyzed tryptophan modification method into a metal-free process, enabling efficient labeling of peptides, proteins, and even cell lysates in hexafluoroisopropanol (HFIP).
