DBCO PEG linker is a class of labeling reagents used in Cu-free click chemistry. The PEG chain increases the hydrophilicity and fine-tunes the properties of the PEGylated molecule.
DBCO PEG linkers are a type of chemical compound that contains both a DBCO functional group and a PEG linker. DBCO linker, or dibenzocyclooctyne, is a reactive functional group that can undergo copper-free click chemistry reactions with azides, enabling the covalent attachment of biomolecules and drugs. PEG, or polyethylene glycol, is a flexible and hydrophilic linker commonly used to improve the pharmacokinetic properties of drugs.
DBCO PEG linkers have become increasingly important in drug research and development due to their ability to facilitate drug conjugation and targeted delivery. The covalent attachment of drugs to biomolecules such as antibodies or peptides can increase their selectivity and efficacy while minimizing off-target effects. Additionally, the use of PEG linkers can improve drug solubility, stability, and circulation time in vivo.
