In general one has to realize that each deprotection reaction is specifically influenced by the chain length of the polymer-bound peptide and by the acutal N-terminal amino acid residue, because of the differences in solvation of the individual amino acids and of the whole peptide in relation to the properties of the support. For this reason, for example, 5.35 N HCl in dimethylsulfoxide/dichloromethane (1 1) was employed [ 115] to deal with the problem of different solvations. In another example, mercaptoethane sulfonic acid [116] was utilized in diluted solution to deprotect N-terminal Boc-tryptophane without harming the indole moiety. 

The N-G/CoPc/GC electrode was evaluated toward the electrooxidation of biologically important thiols (u-cysteine, L-glutathione, and 2-mercaptoethane sulfonic acid). A synergic effect between the N-G and CoPc was observed, with a significant enhancement on the electrocatalytic activity of the modified electrode toward thiols oxidation, which can be attributed to the efficiency of the faster electron transfer between the modified electrode surface and the substrates.
