Fmoc-OtBu-Glu-PEG4-Azide is a peptide linker which may be applied in the development of antibody drug conjugates (ADCs). The t-butyl group can be deprotected under acidic conditions. The Fmoc group can be deprotected under basic conditions to obtain the free amine which can be used for further conjugations. The azide can undergo copper-catalyzed Click Chemistry reactions with alkynes, DBCO and BCN. The PEG4 linker enhances the hydrophilicity of the conjugated compound. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
