生物活性

Strophanthidin is a naturally available cardiac glycoside[1]. Strophanthidin 0.1 and 1 nmol/L increases and 1~100 μmol/L inhibits the Na+/K+-ATPase activities, but Strophanthidin 10 and 100 nmol/L does not affect Na+/K+-ATPase activities in cardiac sarcolemmal[2]. Strophanthidin increases both diastolic and systolic intracellular Ca2+ concentration[3].

體外研究
(In Vitro)

Strophanthidin (0~10 μM; 24 hours; MCF-7, A549, and HepG2 cells) is effective at suppressing the growth of cancer cells and has no toxicity in normal cells[1].
Strophanthidin (0.5 to 500 μM; PBMCs) does not show significant cytotoxicity in PBMCs. Strophanthidin (2 μM; MCF-7 cells) can arrest cell cycle at the G2/M phase[1].
Strophanthidin (MCF-7, A549, and HepG2 cells) is effective at suppressing the growth of cancer cells and has no toxicity in normal cells. Strophanthidin (MCF-7, A549, and HepG2 cells) inhibits the expression of checkpoint and cyclin-dependent kinases in three cancer cells compared to untreated controls. Strophanthidin can modulate the protein localization from the nucleus to the membrane as well as to the cytoplasm. Strophanthidin is a monosaccharide cardiac glycoside with one aglycone portion and without any sugar unit. Strophanthidin induces apoptosis by the attenuation of multiple biochemical signaling pathways and by arresting cell cycle at the G2/M phase through p53-dependent and p53-independent mechanisms[1].

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

以下溶解方案都請(qǐng)先按照 In Vitro 方式配制澄清的儲(chǔ)備液，再依次添加助溶劑：
——為保證實(shí)驗(yàn)結(jié)果的可靠性，澄清的儲(chǔ)備液可以根據(jù)儲(chǔ)存條件，適當(dāng)保存；體內(nèi)實(shí)驗(yàn)的工作液，建議您現(xiàn)用現(xiàn)配，當(dāng)天使用；
以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比；如在配制過程中出現(xiàn)沉淀、析出現(xiàn)象，可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請(qǐng)依序添加每種溶劑： 10% EtOH    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (6.18 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL（飽和度未知）的澄清溶液。

    以 1 mL 工作液為例，取 100 μL 25.0 mg/mL 的澄清 EtOH 儲(chǔ)備液加到 400 μL PEG300 中，混合均勻；再向上述體系中加入 50 μL Tween-80，混合均勻；然后再繼續(xù)加入 450 μL 生理鹽水 定容至 1 mL。

    生理鹽水的配制：將 0.9 g 氯化鈉，溶解于 ddH?O 并定容至 100 mL，可以得到澄清透明的生理鹽水溶液。
  • 方案 二

    請(qǐng)依序添加每種溶劑： 10% EtOH    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (6.18 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL（飽和度未知）的澄清溶液。

    以 1 mL 工作液為例，取 100 μL 25.0 mg/mL 的澄清 EtOH 儲(chǔ)備液加到 900 μL 20% 的 SBE-β-CD 生理鹽水水溶液 中，混合均勻。

    2 g SBE-β-CD（磺丁基醚 β-環(huán)糊精）粉末定容于 10 mL 的生理鹽水中，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.
