Abstract:
Embodiments of the present disclosure relate to methods of preparation of templates for polynucleotide sequencing. In particular, the disclosure relates to linearization of clustered polynucleotides in preparation for sequencing by cleavage of one or more first strands of double-stranded polynucleotides immobilized on a solid support by a transition metal complex, for example, a palladium complex or a nickel complex. Further disclosure relate to linearization of clustered polynucleotides by cleaving one or more second strands of double double-stranded polynucleotides immobilized on a solid support comprising azobenzene linker by Na2S2O4. Nucleotides and oligonucleotides comprising a 3′ phosphate moiety blocking group, and methods of removing the same using a fluoride reagent are also disclosed.
Abstract:
The present disclosure provides methods and systems for detecting multiple different nucleotides in a sample. In particular, the disclosure provides for detection of multiple different nucleotides in a sample utilizing fewer detection moieties than the number of nucleotides being detected and/or fewer imaging events than the number of nucleotides being detected.
Abstract:
A compound has Formula I: A, B, C, D, W, X, Y, and Z are independently selected from hydrogen, optionally substituted C1-C6 alkyl, optionally substituted C1-C6 alkoxy, aryl, aldehyde, protected aldehyde, CH, N, O, S, null, and bond; Q is selected from aldehyde, protected aldehyde, and null, at least one of A, B, C, D, W, X, Y, Z, or Q is an aldehyde or protected aldehyde; the bonds between each of A-B, B-C, C-D, W-X, X-Y, and Y-Z are selected from single bond, double bond, triple bond, and no bond; L is a linker selected from a C1-C12 alkyl, aralkyl, and aryl, any of which is optionally substituted; one or more methylene unit (CH2) of the C1-C12 alkyl is optionally replaced by any combination of oxygen, carbonyl(C═O), and NH; and R1 and R2 are independently selected from —NR3R4, halogen, C1-C8 alkoxy, aralkoxy, alkenyloxy, alkynyloxy, and OCH2CH2CN; R3 and R4 are independently a C1-C4, straight chain or branched alkyl group.

Abstract:
An array includes a support including a plurality of discrete wells, a gel material positioned in each of the plurality of discrete wells, and a quality control tracer grafted to the gel material in each of the plurality of discrete wells. The quality control tracer comprises (a) a cleavable nucleotide sequence comprising a cleavage site and (b) a detectable label; and in some aspects, is a cleavable nucleotide sequence with a detectable label and a non-reactive nucleotide sequence or a primer nucleotide sequence.
Abstract:
There is set forth herein a device comprising structure defining a detector surface configured for supporting biological or chemical substances, and a sensor array comprising light sensors and circuitry to transmit data signals using photons detected by the light sensors. The device can include one or more features for reducing fluorescence range noise in a detection band of the sensor array.
Abstract:
In one example, an unsaturated cyclic dione is coupled to the substrate, and is reacted with an indole or indazole including a first functional group to form a first adduct coupling the first functional group to the substrate. In another example, an unsaturated cyclic dione is coupled to a substrate and reacted with a diene including a functional group to form an adduct coupling the functional group to the substrate. In another example, an indole or indazole is coupled to a substrate, and is reacted with an unsaturated cyclic dione including an oligonucleotide to form an adduct coupling the oligonucleotide to the substrate. In another example, a diene is coupled to a substrate, and is reacted with an unsaturated cyclic dione including an oligonucleotide to form an adduct coupling the oligonucleotide to the substrate.
Abstract:
A method for patterning flow cell substrates using photo-initiated chemical reactions that includes fabricating a planar waveguide flow cell by forming a layer of light coupling gratings on a glass substrate layer; depositing a core layer on the layer of light coupling gratings; depositing a cladding layer on the core layer; and forming nanowells in the cladding layer; silanizing the cladding layer; coating the silanized cladding layer and nanowells with a first group of reactants; introducing a second group of reactants into the nanowells, wherein the second group of reactants includes a target reactant and a light-sensitive photoinitiator system; coupling a light source to the light coupling gratings and directing light internally within the planar waveguide flow cell for photo-initiating a chemical reaction between the first and second groups of reactants, wherein the photo-initiated chemical reaction covalently binds the target reactant to only the bottom portion of each nanowell.
