Article Title: Chemical probes and methods for single-cell detection and quantification of epichaperomes in hematologic malignancies
Abstract: Detection of protein connectivity dysfunctions in biological samples, i.e., informing on how protein-protein interactions change from a normal to a disease state, is important for both biomedical research and clinical development. The epichaperome is an executor of protein connectivity dysfunction in disease, and thus a surrogate for its detection. This chapter will detail on published methods for epichaperome detection and quantification that combine the advantages of multiparameter flow cytometry with those of the PU-FITC fluorescently labeled epichaperome detection probe. It will offer a comprehensive method description that includes the synthesis and characterization of an epichaperome detection probe and of the negative control probe, the preparation of the biospecimen for epichaperome analysis, the execution of the epichaperome detection and quantification assay and lastly, the data acquisition and analysis. The method provides, at single-cell level, the functional signature of cells, differentiating itself from other single-cell methods that provide a catalog of molecules. © 2020 Elsevier Inc.
