Bifunctional Tetrazine-containing Reagents

Tetrazine-containing reagents are suitable for the introduction of

  • a functional group (e.g. Amine or NHS Ester) to Cyclooctene-labeled molecules via Cu-free Click Chemistry
  • an Tetrazine group to various targets e.g. via NHS Ester- or Maleimide-based chemistry

Two Tetrazine versions with different reactivities and stability characteristics are available to meet specific application requirements. Tetrazine reagents are the ideal choice if a rapid reaction kinetic is the key aspect whereas 6-Methyl-Tetrazine reagents are ideally suited if an improved chemical stability is required[1].
