General description: | DMT-dA(tac) Phosphoramidite is a TAC Protected Phosphoramidite. Substitution of standard protecting groups with the labile TAC (tert.- butylphenoxyacetyl) protecting group results in ultra-fast and easy deprotection under mild conditions, suitable for oligonucleotides with baselabile monomers and reporters as well as in-situ synthesis schemes on glass surfaces. Key Features of TAC Chemistry are - • Deprotection of the TAC group is ultra-fast: complete deprotection in concentrated ammonia occurs within 15 minutes at 55 °C or two hours at room temperature • Compatible with the AMA deprotection reagent (a mixture of ≥25% ammonia in water with 40% aqueous methylamine I/I, v/v) • Highly soluble in acetonitrile. No need to add co-solvents such as dimethylformamide or methylene chloride • Suitable for the synthesis of oligomers with base-labile units e.g., dyes and modifiers, because of less exposure to ammonia and the possibility of room temperature deprotection • No change is required in the reagents commonly used for DNA synthesis, except that Proligo′s Fast Deprotection Cap A solution is used instead of Cap A solution • • The application of dA(tac) minimizes depurination and improves the quality of oligonucleotides |
