Fmoc-Lys(Me)3-OH chloride is one of the common N-terminal protected reagents used in the peptide synthesis. Some of the reported examples are:
Synthesis of peptide linkers for monoclonal antibody-auristatin F conjugates.
Preparation of multifunctional reagents with enhanced ionization properties for the analysis of protein modification in human cells and dynamic profiling of protein lipidation.
Sequential peptide ligation to synthesize histone H3 containing a trimethyl lysine residue, with modified tail region.
