    摘要: Propargylethoxyamino nucleosides are disclosed having the structure 1 wherein R1 and R2 are nullH, lower alkyl, or label; B is a 7-deazapurine, purine, or pyrimidine nucleoside base; W1 is nullH or nullOH; W2 is nullOH or a moiety which renders the nucleoside incapable of forming a phosphodiester bond at the 3null-position; and W3 is nullPO4, nullP2O7, nullP3O10, phosphate analog, or nullOH. Additionaly, a primer extension method is provided employing the above propargylethoxyamino nucleosides.

    摘要: Provided are nucleotide-dye conjugates and related compounds in which a dye is linked to a nucleobase directly or indirectly by an anionic linker. The anionic character of the linker is provided by one or more anionic moieties which are present in the linker, such as phosphate, phosphonate, sulfonate, and carboxylate groups. When the dye is a provided as a donor/acceptor dye pair, the anionic linker can be located between the donor and the acceptor, or between the nucleobase and either the donor or acceptor, or both. In one embodiment, conjugates of the invention provide enhanced electrophoretic mobility characteristics to sequencing fragments, e.g., for dideoxy sequencing using labeled terminators.

    摘要: A nucleoside/tide compound having the structure NUCnullLnullSnullLB/LG is described wherein NUC is a nucleoside/tide having a nucleobase portion B, L is a rigid linkage, S is a spacer; and LB/LG is a member of a linkage pair or a label. NUC is attached to L through B such that when B is a purine, L is attached to the 8-position of the purine, when B is 7-deazapurine, L is attached to the 7-position of the 7-deazapurine, and when B is pyrimidine, L is attached to the 5-position of the pyrimidine. In an important aspect of the invention, L has the structure 1 wherein each of n, o and p are integers ranging from 0 to 3, and the sum of n, o and p is at least 2, and each of W, X, Y and Z is selected from the group consisting of carbon and nitrogen. The invention further includes polynucleotide compounds comprising the nucleoside/tide, and primer extension methods utilizing the nucleoside/tide, particularly when used in combination with certain mutant polymerase enzymes.
