Simultaneous single cell measurements of nuclear proteins and RNA with inCITE-seq, with targeted protein measurements using DNA-conjugated antibodies. Single nuclei (n=10,014) of HeLa cells, either untreated or after TNFa treatment, were profiled with inCITE-seq targeting the transcription factor p65. Single nuclei (n=21,583) of the mouse hippocampus after PBS or kainic acid injection were profiled with inCITE-seq targeting TFs p65, c-Fos, and PU.1, as well as the RNA-binding protein NeuN.
