β-Amyloid (1-42) (Amyloid β-peptide (1-42), human TFA, a 42-amino acid peptide that has not been treated with HFIP, is a brain-penetrant amyloid protein fragment, which can be used in research on Alzheimer's disease and Down’s syndrome. β-Amyloid (1-42), human TFA remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human TFA, after being monomericized by HFIP and dissolved in DMSO to form the stock solution, on the one hand, can form soluble oligomers (AβOs) when incubated at 4 °C, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37 °C to form insoluble fibrils, with lower neurotoxicity, and participating in the oxidative damage process. Aβ42 oligomers bind to various neuronal surface receptors (such as PrPc, mGluR5, NMDA receptors, etc.), triggering oxidative stress, calcium homeostasis imbalance, and synaptic toxicity via activating downstream signaling pathways, leading to neuronal dysfunction and death .
