Abstract:
FRET-labeled compounds are provided for use in analytical reactions. In certain embodiments, FRET-labeled nucleotide analogs are used in place of naturally occurring nucleoside triphosphates or other analogs in analytical reactions comprising nucleic acids, for example, template-directed nucleic acid synthesis, DNA sequencing, RNA sequencing, single-base identification, hybridization, binding assays, and other analytical reactions.
Abstract:
The present invention provides methods and compositions for performing illuminated reactions, particularly sequencing reactions, while mitigating and/or preventing photodamage to reactants that can result from prolonged illumination. In particular, the invention provides methods and compositions for incorporating photoprotective agents into conjugates comprising reporter molecules and nucleoside polyphosphates.
Abstract:
Controlled initiation of primer extension in determination of nucleic acid sequence information by incorporation of nucleotides or nucleotide analogs. Preferred aspects include photo-initiated extension through the use of photo-cleavable blocking, groups on termini of primer sequences followed by non-terminating primer extension using nucleotides or nucleotide analogs that are not extension terminators.

Abstract:
The invention provides a novel class of scaffold-based labeled polymerase enzyme substrates. The polymerase enzyme substrates have a multivalent core or scaffold to which is attached fluorescent dye moieties and nucleoside phosphate moities. The polymerase enzyme substrates have multiple fluorescent dye moities and/or multiple nucleoside phosphate moieties. Preferred multivalent cores comprise trifunctional six membered aromatic moities. The invention also provides for sequencing methods and kits with scaffold-based labeled polymerase enzyme substrates.
Abstract:
Compositions, devices, systems and methods for reducing and/or preventing photo-induced damage of one or more reactants in an illuminated analytical reaction by addition of one or more photo-induced damage mitigating agents to the reaction mixture and allowing the reaction to proceed for a period that is less than a photo-induced damage threshold period.
Abstract:
The invention provides a novel class of cyanine dyes that are functionalized with sulfonic acid groups and a linker moiety that facilitates their conjugation to other species and substituent groups which increase the water-solubility, and optimize the optical properties of the dyes. Also provided are conjugates of the dyes, methods of using the dyes and their conjugates and kits including the dyes and their conjugates.
