体外研究
(In Vitro)

当 L1210 细胞暴露于 0.6 μM 2-HBA (bis(2-hydroxy-benzylidene)acetone) 时,NQO1 和谷胱甘肽还原酶的比活性分别增加 6 倍和 1.5 倍。总细胞谷胱甘肽含量也被协调诱导 2.4 倍。在更详细的研究中,发现 NQO1 以浓度依赖性方式由 2-HBA 诱导。用 2-HBA 处理会导致 L1210 野生型细胞及其 Y8 耐药细胞以浓度依赖性方式发生细胞周期停滞和细胞凋亡。2-HBA 还可以激活 caspase-3caspase-10[1]

动物实验:

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (9.39 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (9.39 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Kinase Assay
[1]

Cells (20,000 per well) are grown for 24 h in 96-well plates, then exposed to 2-HBA (bis(2-hydroxybenzylidene)acetone) for either 24 h (for glutathione determination) or 48 h (for determination of enzyme activities). At the end of the exposure period, cells are collected by centrifugation (1500×g for 15 min at 4°C), washed with DPBS, and finally lysed in 0.08% digitonin. An aliquot (25 μL) is used for protein analysis. Activity of NQO1 is determined by the Prochaska test[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Assay
[1]

After exposure to 2-HBA (bis(2-hydroxybenzylidene)acetone) for 24 h, duplicate aliquots of cells (1×106) are collected by centrifugation and washed with cold DPBS. Apoptosis is determined using the Annexin-V-FLUOS assay with simultaneous determination of the necrotic fraction by the uptake of propidium iodide[1].

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.
