DOPE-PEG-Biotin is a bilateral active PEG derivative, also known as PEG (polyethylene glycol) modifier, modified PEG, etc. PEG is a functional group that is currently mainly used for protein drug modification to increase the half-life in vivo and reduce immunogenicity, while also increasing the water solubility of the drug. PEG derivatives have been widely used in pharmaceutical research and development in recent years, and play an important role in the sustained release of drugs. Biotin has a high binding force on avidin or streptavidin, and the biotin/avidin system is widely used in the detection and separation of biomolecules.
