Incorporation into DNA/cDNA by

  • PCR with Taq polymerase in-house data

5-TCO-dUTP is recommended for two-step labeling of DNA/cDNA e.g. by PCR. It is enzymatically incorporated into DNA/cDNA as substitute for its natural counterpart dTTP. The resulting TCO-functionalized DNA/cDNA can subsequently be labeled via Cu(I)-free Click Chemistry (TCO-Tetrazine-Ligation) that offers the choice

  • to introduce a Biotin group (via Tetrazines of Biotin) for subsequent purification tasks
  • to introduce fluorescent group (via Tetrazines of fluorescent dyes) for subsequent microscopic imaging
  • to crosslink the DNA to Tetrazine-functionalized biomolecules e.g. proteins
