产品描述	Chlorpyrifos-oxon, an active metabolite of Chlorpyrifos, is a powerful phosphorylating agent with potent inhibition of AChE activity. It induces cross-linking between tubulin subunits and disrupts microtubule function[4].
体外活性	Treatment of tubulin with 1.5 mM Chlorpyrifos-oxon (CPO) leads to protein aggregation. However, even at 1.5 μM Chlorpyrifos-oxon cross-linked trimers are apparent. Chlorpyrifos-oxon promotes isopeptide bond cross-linking of tubulin monomers to make multimers[2]. In PC12 cells in culture, 24 hours of exposure to Chlorpyrifos at a concentration 10-fold below the concentration that inhibits AChE activity (3.0 μM) impaired neurite outgrowth while Chlorpyrifos-oxon inhibits neurite outgrowth at 1.0 nM[3].
体内活性	Chlorpyrifos-oxon (CPO) is rapidly detoxified by human liver microsomes via CYP-dependent deethylation and dearylation, and by glutathione-S-transferase. In addition, reactions with A-esterases such as paraoxonase 1 (PON 1) or B-esterases such as carboxylesterase and butyrylcholinesterase (BChE) in the liver may rapidly degrade or scavenge Chlorpyrifos-oxon[1]. Chlorpyrifos-oxon (3 mg/kg, ip; once; wild-type mice) treatment shows the dimensions of microtubules from Chlorpyrifos-oxon-treated mice are about 60% of those from control mice. The microtubules from mice exposed to Chlorpyrifos-oxon have covalently modified amino acids and abnormal structure, suggesting disruption of microtubule function[4].

体内实验配液计算器

请在以下方框中输入您的动物实验信息后点击计算，可以得到母液配置方法和体内配方的制备方法：比如您的给药剂量是10 mg/kg，每只动物体重20 g，给药体积100 μL，一共给药动物10 只，您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。

母液配置方法：2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL)，如您需要配置的浓度超过该产品的溶解度，请先与我们联系。

体内配方的制备方法：取 50 μL DMSO 主液，加入 300 μL PEG300，混匀澄清，再加 50 μL Tween 80，混匀澄清，再加 600 μL ddH2O, 混匀澄清。
