體外研究
(In Vitro)

The synthesis of 25-hydroxycholesterol is catalyzed by the enzyme cholesterol 25-hydroxylase, which uses cholesterol and molecular oxygen as substrates and NADPH as a cofactor. 25-hydroxycholesterol is a potent bioactive lipid in the innate and adaptive immune systems[1].

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

動物實驗:

請根據您的 實驗動物和給藥方式 選擇適當的溶解方案。

以下溶解方案都請先按照 In Vitro 方式配制澄清的儲備液,再依次添加助溶劑:
——為保證實驗結果的可靠性,澄清的儲備液可以根據儲存條件,適當保存;體內實驗的工作液,建議您現用現配,當天使用;
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沉淀、析出現象,可以通過加熱和/或超聲的方式助溶

  • 方案 一

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

    Solubility: ≥ 0.5 mg/mL (1.24 mM); 澄清溶液

    此方案可獲得 ≥ 0.5 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 5.0 mg/mL 的澄清 DMSO 儲備液加到 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。
  • 方案 二

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

    Solubility: ≥ 0.5 mg/mL (1.24 mM); 澄清溶液

    此方案可獲得 ≥ 0.5 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 5.0 mg/mL 的澄清 DMSO 儲備液加到 900 μL 20% 的 SBE-β-CD 生理鹽水水溶液 中,混合均勻。

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.
