10x feature barcode technology is a method for adding extra channels of information to cells by running single-cell gene expression in parallel with other assays. This is done by generating additional sequencing libraries within the same droplet containing a single cell. The readout of these libraries are known oligonucleotides that are coupled to cell surface proteins antibodies or sgRNAs. [ http://orcid.org/0000-0002-8674-0039 ]
