Methyltetrazine-PEG4-Alkyne
Methyltetrazine-PEG4-Alkyne is a reagent for converting azido-modified peptides or biopolymers into tetrazine-modified peptides or biopolymers.
Highlights:
- Biocompatible – click reaction occurs efficiently under mild buffer conditions; requires no accessory reagents such as a copper catalyst or reducing agents (e.g. DTT)
- Chemoselective – tetzines and trans-cyclooctene groups do not react or interfere with other functional groups found in biological samples but conjugate to one another with high efficiency
- Unprecedented kinetics – inverse-electron demand Diels-Alder chemistry is the fastest bioorthogonal ligation available, delivering conjugates within 30 min at 1 mg/mL concentrations
- Extended PEG4 Spacer – reduces aggregation, minimizes steric hindrance, and enhances solubility
Methyltetrazine-PEG4-Alkyne is a heterobifunctional reagent that enables simple and efficient conversion of azide-modified peptides into tetrazine-tagged peptides for subsequent ligation to tetrazine-labeled biopolymers. The hydrophilic polyethylene glycol (PEG) spacer arm provides a long and flexible connection that minimizes steric hindrance involved with ligation to complementary TCO-containing molecules.
