Methyltetrazine-PEG4-NHS ester
This product is a heterobifunctional PEG linker containing a methyltetrazine group, a PEG4 spacer, and an NHS ester. It specifically enables rapid tetrazine–TCO click chemistry and efficient amine coupling, offering solubility and medium-length flexibility for bioconjugation and synthesis.
Key Features and Benefits
-
Methyltetrazine Group: Reacts rapidly with trans-cyclooctene (TCO) in IEDDA click chemistry.
-
NHS Ester: Couples efficiently with primary amines to form stable amide bonds.
-
PEG4 Spacer: Enhances solubility and reduces steric hindrance.
-
Dual Reactivity: Combines bioorthogonal click chemistry with amine conjugation.
-
High Purity: Ensures reproducibility in sensitive workflows.
Applications
-
Bioconjugation: Links TCO-modified biomolecules with amine-containing partners.
-
Probe Development: Builds multifunctional probes for diagnostics and imaging.
-
Drug Delivery: Provides PEG scaffolds with click and amine handles.
-
Material Science: Functionalizes nanoparticles, polymers, and surfaces with dual-reactive groups.
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.
