[Fluorescence monitoring of solid-phase peptide synthesis using a quartz reactor-cuvette]

The quartz reactor-cuvette for fluorescent monitoring of the solid phase peptide synthesis consists of a 10 mm diameter quartz tube jacketed in a 14 x 14 mm orthogonal holder and equipped with chemically inert adapters. This allows to use the reactor with almost any standard fluorimeter. Details of the construction are presented. Fluorescence spectra of Fmoc-group, both in solution and on the solid support, are given; effects of concentration quenching of the fluorescence are studied.
