产品活性:β-Amyloid (1-42), human, HFIP-treated 是经过 HFIP 处理后的 β-Amyloid (1-42), human (HY-P1363A)。β-Amyloid (1-42), human (Amyloid β-Peptide (1-42) (human)) 是一种具有42个氨基酸的肽,可引起神经毒性,与阿尔茨海默病的发病机制有关。β-Amyloid (1-42), human 特异性与 LRP1 和 KAI1 基因启动子相互作用。β-Amyloid (1-42), human 可在体外形成寡聚体和纤维,且寡聚体形式比纤维形式具有更强的神经毒性。
生物活性:经HFIP处理的β-淀粉样蛋白(1-42),人源(HY-P1363A)是一种经HFIP处理的β-淀粉样蛋白(1-42),人源(HY-P1363A)。β-淀粉样蛋白(1-42),人源(淀粉样蛋白β-肽(1-42) (人源))是一种由42个氨基酸组成的肽,具有神经毒性,与阿尔茨海默病的发病机制有关。β-淀粉样蛋白(1-42),人源可与LRP1和KAI1等基因的启动子特异性相互作用。β-淀粉样蛋白(1-42),人源可在体外形成寡聚体和原纤维,寡聚体形式的神经毒性比原纤维形式更强[1][2][3][4][5][6]。
体外:β-淀粉样蛋白聚集指南 (以下是我们推荐的方案。此方案仅提供指南,应根据您的具体需要进行修改)。1. 将 β-Amyloid (1-42), human, HFIP-treated 溶解在无水 DMSO 中,浓度为 5 mM,然后涡旋稀释成合适的浓度和缓冲液 (无血清和酚红的培养基)。2. 接下来,将溶液在 4-8°C 下 48 小时。然后将样品在 4-8°C 下以 14000g 离心 10 分钟;可溶性低聚物在上清液中。将上清液稀释 10 -200 倍用于实验。方法因下游应用而异。注意: 聚集形式在溶液中不稳定,建议立即使用。
