Abstract:
A method of sequencing nucleic acids, which can include steps of (a) providing a substrate having a surface having a repeating pattern of features, wherein the features are spatially separated from each other on the surface of the substrate; (b) contacting the repeating pattern of features with a solution of different target nucleic acids to seed a subset of the features that contact the solution, wherein no more than the subset of the features that contact the solution is seeded with the target nucleic acids; (c) amplifying the target nucleic acids at the subset of features; (d) repeating steps (b) and (c) to increase the number of features that are seeded with a nucleic acid, thereby making an array of different nucleic acid colonies; and (e) detecting sequencing reactions at the different nucleic acid colonies on the surface.
Abstract:
A method including (a) providing an amplification reagent including an array of sites, and a solution having different target nucleic acids; and (b) reacting the amplification reagent to produce amplification sites each having a clonal population of amplicons from a target nucleic acid from the solution. The reacting can include simultaneously transporting the nucleic acids to the sites at an average transport rate, and amplifying the nucleic acids that transport to the sites at an average amplification rate, wherein the average amplification rate exceeds the average transport rate. The reacting can include producing a first amplicon from a nucleic acid that transports to each of the sites, and producing subsequent amplicons from the nucleic acid or from the first amplicon, wherein the average rate at which the subsequent amplicons are generated exceeds the average rate at which the first amplicon is generated.
Abstract:
This disclosure provides a method of determining a sequence of nucleotides for a nucleic acid template. The method can include the steps of contacting the nucleic acid template with a conformationally labeled polymerase and at least four different nucleotide species under conditions wherein the conformationally labeled polymerase catalyzes sequential addition of the nucleotide species to form a nucleic acid complement of the nucleic acid template, wherein the sequential addition of each different nucleotide species produces a conformational signal change from the conformationally labeled polymerase and wherein the rate or time duration for the conformational signal change is distinguishable for each different nucleotide species; detecting a series of changes in the signal from the conformationally labeled polymerase under the conditions; and determining the rates or time durations for the changes in the signal, thereby determining the sequence of nucleotides for the nucleic acid template.
