生物活性

Darifenacin (UK-88525) is a selective and orally active M3 muscarinic receptor (M3R) antagonist with a pKi of 8.9. Darifenacin binds >20-fold more specifically to M3R than to other muscarinic receptors. Darifenacin can be used in the study of urinary incontinence and other symptoms of overactive bladder. Darifenacin inhibits tumor growth in colorectal cancer cells and has anti-tumor effects[1][2][3][4][5][6].

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 (5.86 mM); 澄清溶液; 超声助溶

    此方案可获得 2.5 mg/mL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 (5.86 mM); 澄清溶液; 超声助溶

    此方案可获得 2.5 mg/mL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。

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.
