Product profile
2',3'-Dideoxycytidine is classified as modified nucleosides (Formula C9H13N3O3; molecular weight 211.22).
2',3'-Dideoxycytidine can be evaluated in chain-termination, sequencing-control or polymerase-specific substrate studies.
For 2',3'-Dideoxycytidine, polymerase acceptance varies; absence of a 3′-OH prevents further extension after incorporation.
