Biotin-PEG4-amino-t-Bu-DADPS-C3-alykne 

Biotin-PEG4-amino-t-Bu-DADPS-C3-alykne is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs^[1]. Biotin-PEG4-amino-t-Bu-DADPS-C3-alykne is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins^[1].
