Dideoxyguanosine (ddG) is a dideoxyribonucleoside that can only be used to block the 5' end. Use ddC-3' or Spacer C3 to block the 3' end from polymerase extension. ddG is a synthetic analog of deoxyguanosine, in ddG, both the 2- and 3-positions of the ribose have a hydrogen (-H) group substituted for the OH group, whereas in dG, only the 2-position is so substituted. ddG is added to the 5-end of an oligo via 5-to-5 synthesis, using a 2,3-ddG, 5-phosphoramidite. Purification must be by PAGE purification, since such an oligo will not have a trityl group (necessary for RPC purification).

ddC-3' should be used as a 3-end blocking moiety (see ddC technical sheet).
