产品详情	Selamectin，一种半合成的大环内酯，是一种抗寄生虫剂和驱虫剂。Selamectin 激活神经元和咽肌中的谷氨酸门控氯离子通道 (glutamate-gated chloride channels)，以预防恶丝虫，淋巴丝虫和线虫感染。Selamectin 还是一种有效的 P-糖蛋白 (P-glycoprotein) 底物和抑制剂，IC₅₀ 为 120 nM。
生物活性	Selamectin, a semi-synthetic macrocyclic lactone, is a potent parasiticide and anthelminthic. Selamectin activates glutamate-gated chloride channels in neurons and pharyngeal muscles to prevent heartworm, Lymphatic filariae, and nematode infection. Selamectin is also a potent P-glycoprotein substrate and a P-glycoprotein inhibitor with an IC 50 of 120 nM.
性状	Solid
体外研究(In Vitro)	The transport of radiolabelled Selamectin through Caco-2 monolayers shows that Selamectin is P-glycoprotein (P-gp) substrates with a secretory/absorptive ratio of 4.7. Selamectin inhibits the efflux of Rh-123 from peripheral blood lymphocytes (PBL) and the concentration of inhibition is similar to that of Verapamil. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)	A single administration of 6 mg/kg topical Selamectin given every two months could effectively prevent B. malayi infection in cats. Application of topical Selamectin twice a year could block circulating microfilariae. has not independently confirmed the accuracy of these methods. They are for reference only.
运输条件	Room temperature in continental US; may vary elsewhere.
储存方式	Powder -20°C 3 years；4°C 2 years

Data Sheet

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。
