A method of loading beads on a sensor substrate includes applying a suspension including beads to a flow cell defined over a sensor substrate. The sensor substrate includes a plurality of wells. The beads at least partially deposit into the plurality of wells. The method also includes removing liquid from the flow cell, evaporating liquid from the flow cell, for example, by drawing air through the flow cell; and applying a hydrating solution to the flow cell.

Provided herein is technology relating to depositing a material uniformly onto a surface and particularly, but not exclusively, to compositions comprising polymers near their entanglement concentrations and related methods and uses for depositing a material onto a surface uniformly. Accordingly, provided herein is technology that is general, aqueous-based, and does not require re-engineering or chemistry changes to the materials (e.g., beads and/or macromolecules) being deposited. In some embodiments, conventional spotting buffers are modified by dissolving one or more polymers in solution (e.g., aqueous or organic) to provide an even distribution of material (e.g., beads, macromolecules, etc.).

The present invention relates to a device(100) and a method for optically controlling a chemical reaction in a reaction chamber(149) comprising a reagent fluid (114). In a preferred embodiment, the chemical reaction comprises a nucleic acid sequencing on a wiregrid. Based on strong optical confinement of excitation light (110) and of cleavage light (112), the sequencing reaction can be read-out. Stepwise sequencing is achieved by using nucleotides with optically cleavable blocking moieties. After read-out the built in nucleotide is deblocked by cleavage light through the same substrate. This ensures that only bound nucleotides will be unblocked. In order to avoid overheating by cleavage light, the reagent fluid is circulated along the surface of the substrate (101).

The present invention provides methods for replication of nucleic acid molecules distributed on a surface or within a layer by transferring them to a target surface covered with oligonucleotides, and fixation of transferred molecules by hybridization to complementary sequences.
摘要:
A method of retrieving a subset of polynuceotide molecules from a mixture of polynucleotide molecules includes receiving a mixture of nucleotide sequences comprising one or more polynucleotide molecules, synthesizing one or more identifier (ID) regions onto the one or more polynucleotide molecules. The method also includes generating a bead-bound library of one or more beads comprising subsets of identical polynucleotide molecules. Each bead is identified by the ID Sequence of the associated Polynucleotide Sequence. The method further includes sequencing the one or more ID regions of each bead to generate ID Sequence information for each bead, combining the Polynucleotide Sequence information, the one or more ID Sequences, and coordinates of each bead to identify the Polynucleotide Sequence on the bead, and retrieving the bead with its associated Polynucleotide Sequence from the flow cell based on the absolute coordinate position of the bead.
