产品详情
β-Amyloid 22-35 (Amyloid β-Protein 22-35) TFA,β-淀粉样蛋白的 22-35 残基片段,对无血清培养的大鼠海马神经元具有细胞毒性作用。β-Amyloid 22-35 TFA 在中性缓冲液中形成聚集体和典型的淀粉样纤维,类似于 β-淀粉样蛋白。
生物活性
β-Amyloid 22-35 (Amyloid β-Protein 22-35) TFA, the residues 22-35 fragment ofβ-amyloid protein, has a cytotoxic effect on cultured neurons from the rat hippocampus in serum-free medium. β-Amyloid 22-35 TFA forms aggregates and typical amyloid fibrils resembling those of the β-amyloid protein in neutral buffer solution).
性状
Solid
体外研究(In Vitro)
β-Amyloid 22-35 (Amyloid β-Protein 22-35) TFA shows significant cytotoxicity on the rat hippocampal neurons at 40 μg/mL, but exhibits no cytotoxic effect on the glial cells. has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
