This paper describes a novel solid phase peptide synthesis method for the systematic C-terminal modification of cysteine-containing peptides. In this method, cysteine is linked to chloromethylated polystyrene resin by its thiol functionality, followed by protection of the N-terminus and derivatizati

β¦ Synopsis
Two general methods for labeling synthetic peptides with a 5-dimethylamino-1-napthalenesulfonyl idansyl) group at the C-terminal residue using solid phase peptide synthesis (SPPS) are described. Dansylated peptides are ideal substrates for fluorometric proteolytic enzyme assays.

The terminating agent was used to block any N-terminal amino groups which had not reacted in the coupling steps. Blake and Li2 also employed this procedure to assure complete acylation of the N-terminal amino group in the solid-phase synthesis of a heptapeptide. They reported that the acetylation p
