Overview

Bis-PEG10-t-butyl ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.

Appearance:Liquid

IC50& Target:PEGs

In Vitro: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. MCE

Biological Activity:Bis-PEG10-t-butyl ester is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs.
