    摘要: Registration of a patterned flow cell may utilize fiducials comprising sets or groupings of features (e.g., sites, sample wells, nanowells) having known locations and in which the placement of the features is not in accordance with a periodic pattern or is otherwise distinguishable from the periodic pattern of sites present in non-fiducial regions of the flow cell substrate. In certain embodiments the positioning of the sites that are part of the fiducial represent a break or discontinuity in the periodic pattern of sites that are otherwise present on the surface of a patterned flow cell.

    摘要: A sequencing kit includes a plurality of particles and a flow cell. The plurality of particles includes a primer set attached to a surface of each of the plurality of particles; and a flow cell surface attachment mechanism attached to the surface of each of the plurality of particles. The flow cell surface attachment mechanism is selected from the group consisting of a capture primer, an alkene, an alkyne, biotin, and a charged polymer. The flow cell includes a plurality of chemical pads that are spatially separated from one another on a substantially flat substrate surface, each of the chemical pads including chemistry to attach to the surface attachment mechanism.
