Introduction of 166090-74-0 :

β-Amyloid (1-42), (rat/mouse) is a 42-aa peptide, shows cytotoxic effect on acute hippocampal slices, and used in the research of Alzheimer's disease. IC50 & Target:Amyloid-β[1] In Vitro: β-Amyloid Aggregation Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs). 1. Solid Aβ peptide was dissolved in cold hexafluoro-2-propanol (HFIP). The peptide was incubated at room temperature for at least 1h to establish monomerization and randomization of structure. 2. The HFIP was removed by evaporation, and the resulting peptide was stored as a film at -20 or -80 ℃. 3. The resulting film was dissolved in anhydrous DMSO at 5 mM and then diluted into the appropriate concentration and buffer (serum- and phenol red-free culture medium) with vortexing. 4. Next, the solution was aged 48h at 4-8 ℃. The sample was then centrifuged at 14000g for 10 min at 4-8 ℃; the soluble oligomers were in the supernatant. The supernatant was diluted 10-200-fold for experiments. Methods vary depends on the downstream applications. In Vivo: Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

β-Amyloid (1-42), (rat/mouse) can induce Alzheimer's disease[4].

Induction of Alzheimer's disease[4]
Background
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder mainly characterized by the abnormal accumulation of β-amyloid (Aβ) peptide. The oligomeric form of the Aβ peptide as being the critical initiator of neurotoxicity in the AD pathogenesis[4].
Specific Modeling Methods
Rat: Wistar • male • adult, weighing 240-260 g
Administration: 1 μg/μL • Hippocampal injection • single dose
Note
(1) β-Amyloid (1-42) needs to be processed into oligomers before use.
(2) β-Amyloid (1-42) was injected bilaterally into the hippocampus of rat brain in a volume of 1.0 μL over a period of 0.1 μL/min using 1 μL Hamilton syringe.
Modeling Indicators
Indicator changes: Decreased the gene expression level of α7-nAChR and increased the mRNA expression of NMDA receptor 2A, and -2B subunits.
Behavior: β-Amyloid (1-42) aggregates increased the retention time and altered the behavioral response in rats after 15 days of injection.
