DBCO-C4-PEG3-amine
This product is a heterobifunctional linker with a dibenzocyclooctyne (DBCO) group, a C4-PEG3 spacer, and a terminal amine. The DBCO specifically performs ultrafast, copper-free SPAAC click chemistry with azides and the amine couples efficiently with carboxyls or activated esters to form amide bonds. The C4-PEG3 spacer specifically improves solubility, reduces steric hindrance, and balances compactness with flexibility for bioconjugation.
