产品使用指南 技术支持

β-Amyloid (1-42), human, Ala(13C3,15N) TFA 是 13C 和 15N 标记的 β-Amyloid (1-42), human (HY-P1363A)。β-Amyloid (1-42) (Amyloid β-peptide (1-42)), human,一种未经 HFIP 处理过的由 42 个氨基酸组成的肽,是一种具有脑渗透性的淀粉样蛋白片段,可用于阿尔茨海默病和唐氏综合征的研究。β-Amyloid (1-42), human 以单体形式存在时具有抗氧化和神经保护作用。β-Amyloid (1-42), human 在经过 HFIP 单体化处理和用 DMSO 溶成母液后,一方面在 4 ℃ 孵育形成可溶性寡聚体 (AβOs),具有突触毒性和神经毒性;另一方面,可在 37℃ 孵育形成不溶性纤维,神经毒性较低,参与氧化损伤过程。Aβ42 寡聚体可与多种神经元表面受体 (如 PrPc、mGluR5、NMDA 受体等) 结合,通过激活下游信号通路引发氧化应激、钙稳态失衡和突触毒性,导致神经元功能障碍和死亡。

生物活性

β-Amyloid (1-42), human, Ala(13C3,15N) TFA is the 13C and 15N-labeled β-Amyloid (1-42), human (HY-P1363A). β-Amyloid (1-42) (Amyloid β-peptide (1-42)), human, 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 remaining as a monomer exhibits antioxidant and neuroprotective effects. β-Amyloid (1-42), human, 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 ℃, which have synaptic toxicity and neurotoxicity; on the other hand, it can be incubated at 37 ℃ 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[1][1][2][3][4][5][6][7].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
