Recombinant human interleukin-1 beta (h-IL-1 beta) was chemically modified with 4-(N,N-dimethylamino)-4'-isothiocyanatoazobenzene-2'-sulfonic acid (S-DABITC), a water-soluble color reagent specific for lysine labeling. Modified h-IL-1 beta was digested by lysyl endopeptidase. Peptides containing labeled lysines were detected at the visible wavelength (436

A new reversed-phase high-performance liquid chromatography approach to the production of analytical peptide maps by pre-column derivatization using phenylisothiocyanate is described. Tryptic peptide digests were derivatized with phenyl isothiocyanate to form the phenylthiocarbamyl peptides followed by reversed-phase high-performance liquid chromatographic

Group-directed hydrophobic modification of membrane-integrated protein segments by arylisothiocyanates is applied to bacteriorhodopsin. Labeling of purple membrane with phenylisothiocyanate and 4-N,N'-dimethylamino-azobenzene-4'-isothiocyanate results in covalent modification of a unique lysine epsilon-amino group of bacteriorhodopsin. Lysine residue 41, located in the amino-terminal
