Azide-PEG4-aminoallyl-dUTP

For general laboratory use.

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

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

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