Product profile
3',4-Dideoxyuridine is classified as modified nucleosides (Formula C9H12N2O4; molecular weight 212.21 g/mol).
3',4-Dideoxyuridine can be evaluated in chain-termination, sequencing-control or polymerase-specific substrate studies.
For 3',4-Dideoxyuridine, polymerase acceptance varies; absence of a 3′-OH prevents further extension after incorporation.
