Abstract: | The fluorescamine test for the rapid detection of trace amounts of uncoupled products from solid phase peptide synthesis is reported. This novel procedure can detect much smaller amounts of incomplete coupling with greater simplicity than has previously been possible. Since the test is carried out under mild conditions certain side reactions are circumvented. The fluorophor-resins are easily viewed under long wave ultraviolet light, are stable at room temperature, and may be used for quantitative evaluation. |
