DBCO-Sulfo-PEG4-Maleimide
This product is a heterobifunctional linker combining a DBCO group for copper-free SPAAC click chemistry and a maleimide group for selective thiol conjugation. The sulfonated PEG4 spacer enhances solubility, flexibility, and spacing, making it especially effective for bioconjugation, ADC design, and probe development.
Key Features and Benefits:
-
DBCO Group: Enables ultrafast, copper-free click reactions with azides.
-
Maleimide Group: Selectively reacts with thiols for stable cysteine conjugation.
-
Sulfo-PEG4 Spacer: Improves hydrophilicity, solubility, and steric accessibility.
-
Dual Reactivity: Supports orthogonal conjugation strategies.
-
High Purity: Provides reproducibility in advanced workflows.
Applications:
-
Bioconjugation: Couples azide- and thiol-containing biomolecules with high selectivity.
-
ADC Development: Serves as a linker for antibody–drug conjugates.
-
Probe Development: Builds multifunctional probes for imaging and diagnostics.
-
Drug Delivery: Supports targeted conjugation for therapeutic applications.
Storage and Handling:
-
Storage: Store at –20 °C in a tightly sealed, moisture- and light-protected container.
-
Handling: Use anhydrous solvents (e.g., DMF, DMSO); avoid prolonged exposure to moisture to preserve maleimide activity.
This product integrates copper-free click chemistry with thiol-specific conjugation in a sulfonated PEG scaffold, making it a especially versatile tool for targeted bioconjugation, probe design, and therapeutic development.
