[Description]

m-PEG6-CH2COOH is a PEG linker containing a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.
[Biological Activity]

m-PEG5-CH2COOH is a non-cleavable ADC linker for the synthesis of antibody-drug conjugates (ADCs). It is also a PEG-based PROTAC linker, which can be used for PROTAC synthesis.
[in vitro]

ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
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.
