Methods and software for associating mobility probes with target macromolecules are discussed. By encoding the identities of macromolecules of interest with a universal set of tag portions complementary to a universal set of mobility probes, reactions varying in their input starting material may be identified using the same universal set of mobility probes. This allows the universal collection of mobility probes to be used in a target macromolecule-independent manner. Software is used to decode the associations between the mobility probes and a given target macromolecular identity.

Unnatural polymerase substrates that can sustain enzymatic synthesis of double stranded nucleic acids from a nucleic acid template and methods of use

Номер: WO2009134469A1
Принадлежит: Life Technologies

Nucleotide analogs that can sustain the enzymatic synthesis of double-stranded nucleic acid from a nucleic template are described. The nucleotide analogs include: (i) a base selected from the group consisting of adenine, guanine, cytosine, thymine, uracil and their analogs; (ii) a label attached to the base or analog of the base via a cleavable linker; (iii) a deoxyribose; and (iv) one or more phosphate groups. The linker and/or the label inhibits template directed polymerase incorporation of a further nucleotide substrate onto an extended primer strand. In addition, cleavage of the linker leaves a residue attached to the base which is not present in the natural nucleotide and which does not inhibit extension of the primer strand. The nucleotide analogs can therefore be used as reversible terminators in sequencing by synthesis methods without blocking the 3' hydroxyl group. Methods of sequencing DNA using the substrates are also described.

Provided herein are compositions and systems for use in polymerase-dependent, nucleotide transient-binding methods. The methods are useful for deducing the sequence of a template nucleic acid molecule and single nucleotide polymorphism (SNP) analyses. The methods rely on the fact that the polymerase transient-binding time for a complementary nucleotide is longer compared to that of a non-complementary nucleotide. The labeled nucleotides transiently-binds the polymerase in a template-dependent manner, but does not incorporate. The methods are conducted under any reaction condition that permits transient binding of a complementary or non-complementary nucleotide to a polymerase, and inhibits nucleotide incorporation.
