S-Trityl-L-cysteine 與由二級結構元件 (螺旋 a2/環(huán) L5/螺旋 a3) 形成的 Eg5 運動域中的獨特口袋結合[1]。
S-Trityl-L-cysteine (1 -20 μM;持續(xù) 72 小時) 可以劑量依賴性方式介導細胞凋亡和細胞周期停滯。S-Trityl-L-cysteine 介導的細胞凋亡和細胞周期阻滯是通過激活絲裂原激活的蛋白激酶和核因子 kB 信號通路觸發(fā)的[1]。
S-Trityl-L-cysteine 在具有特征性單星形紡錘體的 HeLa 細胞中誘導有絲分裂停滯 (IC50 為 700 nM)[2]

動物實驗:

請根據您的 實驗動物和給藥方式 選擇適當?shù)娜芙夥桨浮?

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(xiàn)用現(xiàn)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(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

    請依序添加每種溶劑: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 1 mg/mL (2.75 mM); 澄清溶液

    此方案可獲得 ≥ 1 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 10.0 mg/mL 的澄清 DMSO 儲備液加到 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

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

    Solubility: ≥ 1 mg/mL (2.75 mM); 澄清溶液

    此方案可獲得 ≥ 1 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 10.0 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。

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.
