Provided herein are methods of identifying a location of an RNA in a sample that include: (a) contacting the sample with an array comprising capture probes, where a capture probe comprises a capture domain and a spatial barcode; (b) releasing the RNA from the sample; (c) extending a 3′ end of the capture probe using the capture domain-bound RNA as a template; (d) generating nick(s) in the extended capture probe-hybridized RNA and performing random-primed DNA synthesis; (e) performing end repair on the second strand DNA molecule; (f) adding a single adenosine nucleotide to the 3′ end of the extended capture probe; (g) ligating a double-stranded sequencing adaptor to the double-stranded DNA product; and (h) determining all or a part of the sequence of the RNA, and the sequence of the spatial barcode, or complements thereof, and using the determined sequences to identify the location of the RNA in the sample.

The invention provides a novel class of cyanine dyes that are functionalized with 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.

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.

Disclosed herein is the identification of human DNA polymerase κ (pol κ) as the polymerase that mediates repair of DNA containing interstrand cros slinks (ICLs). The mechanism of action of a number of chemotherapeutic and antimicrobial agents is the induction of ICLs. Thus, provided herein is a method of enhancing the efficacy of a chemotherapeutic or antimicrobial agent in a subject, including selecting a subject in need of treatment with an ICL -inducing agent and administering to the subject an ICL-inducing agent and a therapeutically effective amount of an inhibitor of pol κ. Also provided is a composition for treating a hyperproliferative disease, an autoimmune disease or an infectious disease, comprising an ICL-inducing agent and an amount of an inhibitor of pol κ sufficient to enhance the efficacy of the ICL-inducing agent. Further provided is a method of identifying a DNA polymerase inhibitor.

摘要:
In various embodiments, the present invention provides fluorescent dyes that are linked to another species through an amino acid or peptide linker. In an exemplary embodiment, the dye is linked to a polyphosphate nucleic acid through an amino acid or peptide linker. These conjugates find use in single molecule DNA sequencing and other applications. In various embodiments, the dye moiety is a cyanine dye. Cyanine dyes that are highly charged, such as those including multiple sulfonate, alkylsulfonate, carboxylate and/or alkylcarboxylate moieties are examples of cyanine dyes of use in the compounds of the invention.
