  • Patent number: 11873483
    Abstract: The disclosure provides methods and compositions useful for labeling of target molecules with origin-specific nucleic acid identifiers (for example, barcodes), which can be used subsequently to identify, quantify, or otherwise characterize a feature or activity of target molecules originating from a particular discreet volume. Such target molecules can include polypeptides expressed by cells, in which nucleic acid molecules encoding the polypeptides are labeled with the same, or matched, origin-specific nucleic acid identifiers.
