TCO-PEG3-Biotin
This product is a multifunctional PEG linker containing a trans-cyclooctene (TCO) group, a PEG3 spacer, and a biotin moiety. It enables rapid bioorthogonal click chemistry with tetrazines while providing high-affinity biotin–streptavidin binding, making it ideal for dual labeling and detection.
Key Features and Benefits
-
TCO Group: Reacts rapidly with tetrazines via inverse-electron-demand Diels–Alder (IEDDA) chemistry.
-
Biotin Moiety: Provides strong affinity binding to streptavidin and avidin systems.
-
PEG3 Spacer: Enhances solubility and minimizes steric hindrance.
-
Dual Reactivity: Combines bioorthogonal click chemistry with affinity-based capture.
-
High Purity: Ensures reliable and reproducible results.
Applications
-
Bioconjugation: Links tetrazine-modified molecules with biotin-binding systems.
-
Probe Development: Builds multifunctional probes for imaging and diagnostics.
-
Drug Delivery: Provides scaffolds with dual click and affinity handles.
-
Material Science: Functionalizes surfaces and nanostructures with bioorthogonal and affinity chemistries.
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.
