Abstract

In situ hybridization of oligonucleotide probes to intracellular RNA allows quantification of predefined gene transcripts within millions of single cells using cytometry platforms. Previous methods have been hindered by the number of RNA that can be analyzed simultaneously. Here we describe a method called proximity ligation assay for RNA (PLAYR) that permits highly multiplexed RNA analysis that can be combined with antibody staining. Potentially any number of RNA combined with antigen can be analyzed together, being limited only by the number of analytes that can be measured simultaneously.
