Precise immunofluorescence canceling for highly multiplexed imaging to capture specific cell states

Abstract Cell states are regulated by the response of signaling pathways to receptor ligand-binding and intercellular interactions.High-resolution imaging has been attempted to explore the dynamics of these processes and, recently, multiplexed imaging has profiled cell states by achieving a comprehensive acquisition of spatial protein information from cells.However, the specificity of antibodies is still compromised miracle academy clothing when visualizing activated signals.

Here, we develop Precise Emission Canceling Antibodies (PECAbs) that have cleavable fluorescent labeling.PECAbs enable high-specificity sequential imaging using hundreds of 15-eg1053cl antibodies, allowing for reconstruction of the spatiotemporal dynamics of signaling pathways.Additionally, combining this approach with seq-smFISH can effectively classify cells and identify their signal activation states in human tissue.

Overall, the PECAb system can serve as a comprehensive platform for analyzing complex cell processes.
