Publication number: 20230313297Abstract: Compositions, kits and methods for detecting a plurality of targets are provided herein. A probe-set composition is provided, including one or more first probes and one or more second probes. Each of the first probe includes a nucleic acid sequence complementary to a nucleic acid barcode of a corresponding target-specific binding partner, a first label, and a cleavage site for a first cleavage agent, wherein the first cleavage agent is capable of releasing the first label. Each of the second probes includes a nucleic acid sequence complementary to a nucleic acid barcode of a corresponding target-specific binding partner, a second label, a quench moiety that renders the second label undetectable, and a cleavage site for the first cleavage agent.
