5-TCO-PEG4-dUTP

• Catalog Number: orb1734975
• Category: Tools
• Description: 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 subse-quent 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.
