Pep2-8 is primarily utilized in research focused on understanding and modulating protein-protein interactions, particularly in the context of neurodegenerative diseases. It is often employed in studies investigating the aggregation of amyloid-beta peptides, which are implicated in Alzheimer's disease. By interfering with these interactions, Pep2-8 helps researchers explore potential therapeutic strategies to prevent or reduce amyloid plaque formation. Additionally, it serves as a valuable tool in biochemical assays to study the mechanisms of peptide aggregation and its impact on cellular function. Its application extends to the development of diagnostic methods and drug discovery efforts targeting amyloid-related pathologies.
