Abstract: Provided herein are compositions, kits, and methods for collection, integration and analysis of various facets of information from tissues at the cellular or subcellular level. Information includes spatial mapping from nucleic acid barcodes to reconstruct location of nodes of nucleic acid barcode generation in a sample. In some workflows, light-based technologies are incorporated for an additional layer of selective spatial tagging of regions. In further steps, such tags are optionally analyzed by high throughput imaging or Next Generation Sequencing.

Abstract: Provided herein are compositions, kits, and methods for collection, integration, and analysis of spatially based information from tissues at the cellular or subcellular level. Layers of information include, without limitation, gene expression, morphology, nucleic acids, and proteins. In some workflows, light-based technologies are incorporated for selective spatial barcoding of regions. In further steps, such barcoded tags are optionally analyzed by high throughput Next Generation Sequencing.

Abstract: Provided herein are compositions, kits, and methods for nucleic acid barcoding. The barcode compositions provided herein can be used to linearly, combinatorially, or spatially barcode a plurality of targets in a sample. Also provided herein is a device for use in a barcoding method provided herein comprising a light source and a sample holder.

Abstract: Provided herein are compositions, kits and methods for synthesis of nucleic acids. Also provided herein are compositions and methods for synthesizing strands of nucleic acid across different nucleic acid back-bones hybridized together using a strand displacing polymerase.
