请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
储备液的保存方式和期限：-80°C, 6 months; -20°C, 1 month。-80°C 储存时，请在 6 个月内使用，-20°C 储存时，请在 1 个月内使用。

In Vivo:

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

• 1.

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

  Solubility: ≥ 2.5 mg/mL (2.31 mM); Clear solution

  此方案可获得 ≥ 2.5 mg/mL (2.31 mM，饱和度未知) 的澄清溶液。

  以 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；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。

  将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液

MV4;11 or HL60 cells are incubated with MZP-55 at the desired concentration for 48 h on a clear-bottom 384-well plate. Cells are kept in RPMI medium supplemented with 10% FBS, l-glutamine, penicillin, and streptomycin. Initial cell density is 3 × 10⁵ per mL. Cells are treated with various concentrations of MZP-55 or 0.05% DMSO. After treatment, cell viability is measured with cell viability assay kit. Signal is recorded. Data are analyzed with Graphpad Prism software to obtain EC₅₀ values of each MZP-55^[1].
