TCO-PEG5-amine
This product is a bifunctional PEG linker containing a trans-cyclooctene (TCO) group, a PEG5 spacer, and a terminal primary amine. It enables rapid tetrazine click chemistry and provides an amine handle for amide coupling, making it especially versatile for bioconjugation.
Key Features and Benefits
-
TCO Group: Reacts rapidly with tetrazines via inverse-electron-demand Diels–Alder (IEDDA) click chemistry.
-
Primary Amine: Couples with carboxyls, NHS esters, or activated linkers.
-
PEG5 Spacer: Enhances solubility and reduces steric hindrance.
-
Dual Reactivity: Combines TCO click chemistry with amine conjugation.
-
High Purity: Ensures reliable results in sensitive applications.
Applications
-
Bioconjugation: Links TCO-modified and amine-reactive biomolecules.
-
Probe Development: Builds multifunctional probes for imaging and diagnostics.
-
Drug Delivery: Provides PEGylated scaffolds with orthogonal conjugation handles.
-
Material Science: Functionalizes polymers and nanoparticles with dual reactivity.
Storage and Handling
-
Storage: Keep 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.
