生物活性

GSK481 is a highly potent, selective, and specific receptor interacting protein 1 (RIP1) kinase inhibitor with an IC50 of 1.3 nM, which inhibits Ser166 phosphorylation in wild-type human RIP1 (IC50=2.8 nM). GSK481 also exhibits excellent translation in the U937 cellular assay with an IC50 of 10 nM[1].

IC50 & Target

IC50: 1.3 nM (RIP1), 2.8 nM (Ser166 phosphorylation in wild-type human RIP1)[1]

——為保證實驗結(jié)果的可靠性,澄清的儲備液可以根據(jù)儲存條件,適當保存;體內(nèi)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: ≥ 2.5 mg/mL (6.62 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。

    1 mL 工作液為例,取 100 μL 25.0 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: 2.5 mg/mL (6.62 mM); 懸濁液; 超聲助溶

    此方案可獲得 2.5 mg/mL的均勻懸濁液,懸濁液可用于口服和腹腔注射。

    1 mL 工作液為例,取 100 μL 25.0 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.
