Method of solid-phase nucleic acid synthesis and solution composition for solid-phase nucleic acid synthesis

This invention is intended to discover a novel solvent that can be used as an alternative to toluene in the step of deprotection in the method of solid-phase nucleic acid synthesis. With the use of such novel solvent, various problems caused by the use of toluene are dissolved. This invention is also intended to provide a method of solid-phase nucleic acid synthesis in which protected nucleoside phosphoramidites in which a protective group is bonded to a hydroxyl group at the 5′position or the 3′ position of a nucleoside are sequentially bound on a solid phase carrier, where a reaction of removing the protecting group from the protected nucleoside phosphoramidite is carried out in a solution comprising an acid with a pKa of 0.2 to 0.8 and acetonitrile.

PROTECTED DYE-LABELED REAGENTS

Labeled nucleotide analogs comprising at least one avidin protein, at least one dye-labeled compound, and at least one nucleotide compound are provided. The analogs are useful in various fluorescence-based analytical methods, including the analysis of highly multiplexed optical reactions in large numbers at high densities, such as single molecule real time nucleic acid sequencing reactions. The analogs are detectable with high sensitivity at desirable wavelengths. They contain structural components that modulate the interactions of the analogs with DNA polymerase, thus decreasing photodamage and improving the kinetic and other properties of the analogs in sequencing reactions. Also provided are nucleotide and dye-labeled compounds of the subject analogs, as well as intermediates useful in the preparation of the compounds and analogs. Compositions comprising the compounds, methods of synthesis of the intermediates, compounds, and analogs, and mutant DNA polymerases are also provided.
