BA 0054 5'-Fluorescein CEP C46H58N3O10P  204697-37-0  For the installation of fluorescein at the 5'-terminus of an oligonucleotide, the phosphoramidite "6-FAM" (5'-Fluorescein CEP, BA 0054), is a popular choice. The lack of a trityl group precludes multiple additions or assaying the coupling step. For those interested in a trityl-bearing version of 6-FAM, we offer Fluorescein II CEP ("6-FAM II", BA 0253), which features the same tether length as 6-FAM, but includes a DMT group, and Fluorescein III CEP ("6-FAM III", BA 0334) with a DMT on a 1,3-diol framework.

 		 Useful for the installation of fluorescein at the 5'-terminus of an oligonucleotide.  6-FAM

CEP		 C42H52N7O7P  642462-81-5  Guanine bases in DNA are susceptible to N-alkylation by various carcinogens, leading to miscoding and mutagenicity. Choi and Guengerich have prepared a series of N2-alkyl-2'-deoxyguanosine phosphoramidites where the alkyl group ranges in size from methyl to anthracenylmethyl for studies on the effect of the size of these groups on the catalytic efficiency and fidelity of various DNA polymerases.1 We offer the N2-methyl- (BA 0249), N2-ethyl- (BA 0076), and N2-isobutyl-dG (BA 0250) phosphoramidites1 as well as two additional bulkier choices, the N2-neopentyl version (BA 0200), and the N2-benzyl version (BA 0337) . Researchers may find this "steric tool box" useful for probing the steric requirements at N2 of dG in various applications.
