5-TCO-PEG₄-dUTP

For general laboratory use.

Please centrifuge briefly before opening (volume ≤2 ml).

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 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
