Beta-Amyloid (17-40) HFIP treated peptide (0.1 mg)

Neurodegeneration and Alzheimer’s research: Used to investigate how Beta amyloid (1-40) production, clearance, and aggregation contribute to Alzheimer’s or other neurodegenerative diseases like dementia. Amyloid aggregation and plaque formation studies: Serves as a model for studying β-sheet formation and the progression from oligomers to protofibrils and mature fibrils using structural techniques such as NMR, AFM, and cryo-EM. Mechanisms of neurotoxicity: Employed to analyze how soluble oligomers disrupt synaptic signaling, induce oxidative stress, trigger apoptosis, and impair neuronal membrane integrity. Cerebrovascular research: Used to study the impact of 40-amino-acid beta amyloid isoform on cerebral blood vessels, including vascular dysfunction, impaired blood-flow regulation, and mechanisms underlying cerebral amyloid angiopathy (CAA). Neuroinflammation research: Applied in studies exploring microglial activation, cytokine release, and inflammatory responses triggered by aggregated beta amyloid species. Biomarker development and diagnostics: Supports the development of CSF and blood biomarkers (e.g., Aβ (1-42)/Aβ (1-40) ratio) that strongly correlate with amyloid PET imaging, providing an indirect link to PET-based Alzheimer’s diagnosis. Anti-amyloid drug discovery and therapeutic development: Utilized to screen inhibitors of aggregation, test monoclonal antibodies targeting Aβ peptides, evaluate peptide-based therapeutics, and model the effects of candidate compounds that reduce toxicity or promote clearance. Systemic health research: Employed in studies investigating links between circulating Amyloid-beta (1-40) levels and systemic disorders such as kidney dysfunction and cardiovascular diseases. Physiological function studies: Used to examine potential normal roles of low-level Beta-amyloid (1-40) in synaptic regulation, neural development, and antioxidant activity. Comparison studies with Amyloid beta (1-42): Used in comparison studies with Amyloid beta (1-42) to evaluate differences in concentration, aggregation behavior, and diagnostic value in Alzheimer’s research.

Alzheimer’s and neurodegenerative research: Used as a defined model of early Beta-amyloid (1-40) oligomers to study initial pathogenic events in Alzheimer’s disease and related neurodegenerative conditions. Amyloid aggregation and plaque formation studies: Provides a controlled starting point for tracking the conversion of dimers into higher-order oligomers and protofibrils using structural techniques such as NMR, AFM, and TEM. Early neurotoxicity and synaptic dysfunction studies: Enables analysis of how stabilized amyloid beta dimers disrupt synaptic signaling, impair membranes, induce oxidative stress, and contribute to neuronal dysfunction. Memory and LTP impairment studies: Applied in neuronal and animal models to investigate how amyloid beta dimers impair long-term potentiation and drive early cognitive decline. Seeding and propagation research: Used to examine how defined amyloid beta dimers act as seeds that accelerate aggregation or influence amyloid propagation behavior. Protein-peptide, receptor, and membrane interactions: Applied to study how early the 40-amino-acid long amyloid beta oligomers bind to lipid bilayers, neuronal receptors (e.g., PrP), and other membrane components involved in amyloid beta toxicity. Anti-amyloid drug discovery and therapeutic development: Utilized for screening aggregation inhibitors, testing monoclonal antibodies, and evaluating small molecules targeting early oligomer formation or toxicity. Structure-function analyses: Supports detailed studies of dimer structure, stability, and conformational changes, linking specific structural features to downstream toxicity. Comparative studies: Enables direct comparison with monomeric amyloid beta peptides to assess differences in aggregation, toxicity, and oligomer behavior.
