Qstatin
目录号: PL12051 纯度: ≥98.0%
QStatin 是一种有效且选择性的 SmcR 抑制剂 (V. harveyi LuxR 同源物),EC50 值为 208.9 nM,与 SmcR 紧密结合并改变了蛋白质的柔韧性,从而改变了其转录调控活性。QStatin 在多种弧菌中显示 pan-QS 抑制剂活性,并减弱其在水生宿主中的毒力。QStatin 可用于水产养殖的可持续性抗弧菌病药物。

生物活性
QStatin is a potent and selective inhibitor of SmcR (V. harveyi LuxR homologue) with an EC 50 of 208.9 nM, binding tightly to SmcR and changes the flexibility of the protein, thereby altering its transcription regulatory activity. QStatin shows pan-QS (Vibrio quorum sensing) inhibitor activity in diverse Vibrio species and attenuates their virulence in an aquatic host. QStatin may be a sustainable antivibriosis agent useful in aquacultures.

体外研究(In Vitro)
QStatin (0.001 μM-10 μM; 5 hours) inhibits SmcR activity measured by the RLU level for V. vulnificusWT (pBB1), reveals EC50 of 208.9 nM.
QStatin (5 μM-50 μM; 16 hours) reduces the activities of SmcR-activated virulence factors (protease and elastase) in V. vulnificus in a dose dependent manner.
QStatin (5 μM-50 μM; 16 hours) has no effect on the cellular levels of SmcR, indicating that QStatin does not affect the expression or stability of SmcR.
has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
