DBCO-PEG5-DBCO CAS: 2363130-04-3 is a homofunctional DBCO crosslinker with a hydrophilic PEG5 spacer. It clicks with azide-tagged biomolecules in copper-free reactions, forming stable, flexible linkages. Used mainly in drug delivery systems, it efficiently binds drugs or imaging agents to azide molecules. This increases selectivity, stability, and minimizes off-target effects.
AxisPharm offers 5000+ PEG Linkers with high purity. Different kinds of PEG Reagents may be available by custom synthesis.
