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

Cell Viability Assay[1]

Cell Line: HUVECs cells
Concentration: 2 nM, 10 nM, 20 nM and 200 nM
Incubation Time: 30 minutes
Result: Low concentrations (2 nM, 10 nM) rapidly induced tubulin depolymerization in HUVECs.
体内研究
(In Vivo)

PlinabuLin (0 mg/kg-15 mg/kg;腹膜内注射;雌性 CDF1 和 C3H/He 小鼠) 诱导肿瘤灌注的时间和剂量依赖性降低。KHT 肉瘤比 C3H 肿瘤对 Plinabulin 的抗肿瘤作用更敏感,而两种模型的放射反应均得到增强[3]

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

Animal Model: Female CDF1 mice (10-14-week-old) with C3H mammary carcinoma; Female C3H/HeJ mice with KHT sarcoma cells (8-weeks-old)[3]
Dosage: 0 mg/kg, 1.5 mg/kg, 2.5 mg/kg, 5 mg/kg, 7.5 mg/kg, 10 mg/kg, 12.5 mg/kg, 15 mg/kg;
0.02 mL/g mouse body weight in CDF1 mice and 0.01 mL/g body weight for C3H/HeJ mice
Administration: Intraperitoneal injection; 0 huor, 1 huor, 3 hours, 6 huors, 24 huors
Result: Induced a time- and dose-dependent decrease in tumour perfusion. The KHT sarcoma was more sensitive than the C3H tumour to the anti-tumor, while radiation response was enhanced in both models.

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 (7.43 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 (7.43 mM); 悬浊液; 超声助溶

    此方案可获得 2.5 mg/mL的均匀悬浊液,悬浊液可用于口服和腹腔注射。

    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。

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.
