DBCO-PEG24-MAL is a long, single molecular weight, discrete PEG crosslinking reagent. The dibenxylcyclooctyne moiety permits strain promoted azide-alkyne cycloaddition known as "copper free click chemistry. The maleimidopropyl functional groups forms thiol-ether linkage with sulfhydryl groups. The hydrophilic, non-immunogenic PEG spacer in DBCO-PEG24-MAL provides the benefits of PEG without the analystical headaches of PEG dispersity.
