"WebDec 1, 2002 · The synthetic peptides were labeled using a fluorescein amine (FS) labeling kit (Panvera, Madison, WI). The labeling reagent is a succinimidyl ester of fluorescein, which selectively forms an amide bond with N-terminal amino group of peptides or proteins at neutral pH; this reagent reacts more rapidly and forms a more stable derivative than FITC.
