Applications:
Incorporation into DNA/cDNA by

• PCR with Taq polymerase ^{in-house data}

Description:
5-DBCO-PEG₄-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 DBCO-functionalized DNA/cDNA can subsequently be labeled via Cu(I)-free click chemistry that offers the choice

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