Medchemexpress LLC DBCO-NHCO-PEG2-maleimide | 2698339-31-8 | 97.7% | C32H34N4O7 | 10MG
DBCO-NHCO-PEG2-maleimide is a bifunctional click-chemistry linker that couples a dibenzocyclooctyne (DBCO) moiety for strain-promoted alkyne-azide cycloaddition (SPAAC) with a maleimide group for thiol-selective conjugation. The PEG2 spacer improves solubility and flexibility, making it suitable for bioconjugation and linker synthesis.
- Enables copper-free SPAAC click chemistry
- Provides thiol-selective maleimide conjugation
- PEG2 spacer improves aqueous solubility
- Suitable for bioconjugation and linker synthesis
- High reported purity (~97.7%)
- Stable as powder at -20°C for long-term storage
