Product Information

Description	SPDP-PEG4-COOH is a PEG-based PROTAC linker which is applicated in medical research, drug-release, nanotechnology and new materials research, cell culture. It contains SPDP crosslinker and carboxylic acid moieties. SPDP is reactive toward amine and thiol groups and contains a cleavable disulfide bond. Its membrane permeability allows for intracellular crosslinking reactions. The terminal caboxylic acid can react with primary amines in the presence of activators such as EDC and DCC to form stable amide bonds. The water solubility properties of PEG linkers is enhanced by longer PEG chains.
