Figure 5-13. Thin-layer chromatography separation of mixture of peptides labeled with fluorescamine using poly(butyl acrylate-co-ethylene dimethacrylate) monolithic layer attached to a glass plate using 0.1 vol% trifluoroacetic acid in 45 vol% aqueous acetonitrile as the mobile phase (left) and matrix-assisted laser desorption/ionization time-offlight mass spectrometryspectra of fluorescently labeled [Sar1,Ile8]-angiotensin II, angiotensin II, and neurotensin obtained “from-plate” using a-cyano-4-hydroxycinnamic acid as matrix.
