Generating spatial array of capture probes on substrate
A recently granted patent (Publication Number: US11926867B2) discloses a method for generating a spatial array on a substrate. The method involves immobilizing two sets of primers on the substrate, with one set containing functional domains and a sequence complementary to a hybridization domain, while the other set contains a sequence complementary to a capture domain. A template oligonucleotide with specific domains is then provided, which hybridizes to the first set of primers, leading to the generation of a capture probe. The template oligonucleotide is then released, resulting in the formation of the spatial array.
Furthermore, the method includes amplifying the capture probe to create a clonal cluster of capture probes. This amplification process involves hybridization, extension, and releasing steps to generate multiple copies of the template oligonucleotide immobilized on the substrate. The method also incorporates unique molecular identifiers (UMIs) in the template oligonucleotide for sequencing purposes. The patent covers various aspects of the method, including primer immobilization ratios, primer distances, bead attachment, substrate composition, and sequencing techniques for determining the spatial barcode sequence of the generated capture probes. The disclosed method offers a novel approach to spatial array generation with potential applications in molecular biology research and diagnostics.
