Fmoc-L-Lys(N3-Gly)-OH is a click chemistry reagent containing a lysine-containing azidoacetyl group building-block for SPPS and can be used for various biochemical studies[1].
The azide function is widely used for coupling to alkyne-containing fragments via the renowned Click reaction. Polyglycine fragments containing up to 7 glycines are reported to bind to surfaces and have potential application in nanotechnology constructs: constructs of Gly7-NHCH2-fragment containing peptides bind on mica surface in aqueous solution[1][2].
