DNA synthesis monitoring (potentially)

5-DBCO-dU (5-Dibenzylcyclooctyne-2'-deoxyuridine) can potentially be used as a replacement for BrdU (5-Bromo-2'-deoxyuridine) or the copper-catalyst requiring 5-EdU (5-Ethynyl-2'-deoxyuridine) to measure de novo DNA synthesis in proliferating cells.
5-DBCO-dU is cell permeable and may incorporate into replicating DNA instead of its natural analog thymidine.

The resulting DBCO-functionalized DNA can subsequently be detected via Cu(I)-free Click Chemistry that offers the choice to

  • introduce a Biotin group for subsequent purification tasks (via Azides of Biotin)
  • introduce a fluorescent group for subsequent microscopic imaging (via Azides of fluorescent dyes).
