1. A method of identifying an expression profile in a single cell of a population of cells, comprising:
- a) contacting a population of cells with a plurality of antibodies under conditions that promote specific binding of the antibodies to target antigens of the cells, wherein each antibody in the plurality is capable of binding to a unique target antigen in one or more cells, wherein each antibody is conjugated to an oligonucleotide, and wherein the oligonucleotide comprises a unique molecular identifier sequence and an antibody identifier sequence corresponding to the unique target antigen;
b) separating single cells of the population into individual compartments;
c) amplifying the unique molecular identifier sequences and antibody identifier sequences in each individual compartment; and
d) analyzing the amplified unique molecular identifier sequences and antibody identifier sequences to identify the expression profile of each single cell.
