Protein-protein interactions (PPIs) are fundamental to a wide array of biological processes, from cellular signaling to the regulation of metabolic pathways. Understanding these interactions is crucial for drug discovery, disease research, and the development of therapeutic strategies. One of the most advanced methods for studying PPIs is Fusion Protein Interaction Analysis. This service, combined with techniques like Mass Spectrometry Identification of Interacting Proteins, Pull-Down Combined with MS Analysis, and Protein Interaction Analysis Services, provides powerful tools to researchers seeking to unravel complex protein networks.
