    Abstract: In some aspects, provided herein are methods for analyzing a nucleic acid comprising first and second regions of interest flanking an adaptor region, comprising hybridizing an anchor to the adaptor region, analyzing the first region of interest from one end of the anchor using probe ligation (e.g., sequencing-by-ligation), and binding a polymerase to the other end of the anchor and optionally incorporating a nucleotide and/or analog thereof into the anchor by the polymerase using the second region of interest or a probe bound thereto as a template. In some embodiments, the second region of interest is used as a template for sequencing-by-synthesis. In some embodiments, spatially resolved detections of analytes are performed at a cellular or sub-cellular resolution which involve correlating signals associated with analytes with specific spatial locations in a biological sample.

    Abstract: Provided herein are methods of preparing a spatial array and methods for associating specific sample analytes with spatial locations in the spatial array. Provided herein are methods for preparing a spatial array using a plurality of primers attached to a substrate to guide a plurality of features to specific locations on the spatial array. In a non-limiting example, a plurality of primers on a substrate can be used to guide a plurality of first features that include capture probes onto the substrate. A plurality of second features that are configured to hybridize to the first features and also include capture probes are added to the substrate.
