(2S)-6-[(3',6'-dihydroxy-3-oxospiro[2-benzofuran-1,9'-xanthene]-5-yl)carbamothioylamino]-2-(9H-fluoren-9-ylmethoxycarbonylamino)hexanoic acid

Fmoc-Lys(5-FITC)-OH is a marker for polypeptides or proteins. FITC is a fluorescence probe for the labeling of amines. FITC is a pH- and Cu2+-sensitive fluorescence dye[1][2][3].
