TCO-PEG12-DBCO
This product is a heterobifunctional PEG linker containing a trans-cyclooctene (TCO) group, a PEG12 spacer, and a dibenzocyclooctyne (DBCO). It specifically enables rapid tetrazine ligation and copper-free click chemistry, offering solubility, long-chain flexibility, and dual orthogonal reactivity.
Key Features and Benefits
-
TCO Group: Reacts rapidly with tetrazines via IEDDA bioorthogonal click chemistry.
-
DBCO Group: Couples with azides through SPAAC copper-free click chemistry.
-
PEG12 Spacer: Provides hydrophilicity, solubility, and extended spacing.
-
Dual Orthogonal Handles: Enables two independent bioorthogonal reactions.
-
High Purity: Ensures reproducibility in sensitive conjugation workflows.
Applications
-
Bioconjugation: Links tetrazine- and azide-modified biomolecules.
-
Probe Development: Builds multifunctional probes for diagnostics and imaging.
-
Drug Delivery: Provides PEG scaffolds with dual bioorthogonal handles.
-
Material Science: Functionalizes nanoparticles, polymers, and surfaces with orthogonal reactivity.
Storage and Handling
-
Storage: Store at –20 °C in a sealed, light- and moisture-protected container.
-
Handling: Use anhydrous solvents such as DMF or DMSO; avoid prolonged exposure to moisture.
This product integrates TCO and DBCO bioorthogonal chemistries in a PEG12 scaffold, specifically offering solubility, flexibility, and versatile dual conjugation capability.
