The CITE-seq workflow combines conventional single-cell transcriptomic analysis with simultaneous analysis of cell surface protein expression using oligonucleotide-conjugated antibodies. This addition of immunophenotyping to mRNA data allows for a more detailed characterization of single-cell heterogeneity and can help to identify markers for the prospective isolation of transcriptionally defined novel cell subsets. Here, we describe the workflow for the preparation of human cord blood mononuclear cells and CD34+-enriched hematopoietic progenitors for the simultaneous characterization of protein and RNA using the commercially available TotalSeq™ antibodies from BioLegend and the droplet-based single-cell RNA-seq commercial platform from 10x Genomics.
