US Patent 11408896 Methods for discovering protein-protein interactions

An embodiment relates to a method, comprising: obtaining a biological sample, performing a protein complex immunoprecipitation (Co-IP) on the sample, performing a reverse phase protein array (RPPA) on the sample after performing the protein complex immunoprecipitation, and identifying one or more protein complexes. A further embodiment relates to a method of treatment, comprising: obtaining a tissue sample from a patient, performing Co-IP then RPPA on the sample, identifying a protein complex, determining whether the protein complex comprises known protein drug targets, and treating the patient with a drug that interacts with the known protein drug targets.
