Amino-PEG4-bis-PEG3-propargyl

Amino-PEG4-bis-PEG3-propargyl functions as a cleavable 6-unit PEG ADC linker in the creation of antibody-drug conjugates (ADCs) [1]. As a click chemistry reagent, it features an Alkyne group that participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC) with Azide-containing molecules.
