Abstract: Methods and Kits for analyzing macromolecules, including peptides, polypeptides, and proteins, employing nucleic acid encoding are disclosed. The sample analysis kits employ nucleic acid encoding and/or nucleic acid recording of a molecular interaction and/or reaction, such as recognition events (e.g., between an antigen and an antibody, between a modified terminal amino acid residue, or between a small molecule or peptide therapeutic and a target, etc.). Assays that do not require the cyclic transfer of information between a coding tag and a recording tag are also disclosed, including single cycle assays.

Abstract: The present disclosure relates to methods and kits for generating single cell barcodes and imparting them to the constituent molecules within a single cell. Additionally, methods to overlay sample barcode and spatial barcode information onto the single cell barcodes are also described. Generation of single cell barcodes is achieved by labeling the genomic DNA of a cell/nucleus with a small handful, preferably just a one or two cellular barcode probes (CBP) that can be amplified and propagated to label the constituent molecules within the cell. The disclosure finds utility in applications such as characterization of cellular heterogeneity, comprehensive profiling of tissue composition, characterization of adherent cells, discovery of new cell subtypes and functions of individual cells in the context of its microenvironment, and others.
