Selamectin   中文名称: 色拉菌素 EP标准品

放射性标记的塞拉菌素被发现是一种 P-糖蛋白 (P-gp) 底物，当它转运穿过 Caco-2 单层时，其分泌/吸收比为 4.7。在外周血淋巴细胞 (PBL) 中，塞拉菌素抑制 Rh-123 外流的剂量与维拉帕米的抑制效果相当 [2]。

每两个月局部使用赛拉菌素 6 mg/kg 一次，可以成功避免 B。猫感染马来语。每年两次，外用赛拉菌素可以阻止微丝蚴的循环[1]。

Selamectin is a milbemycin.
Selamectin is a topical parasiticide and antihelminthic used on dogs and cats to treat and prevent infections of heartworms, fleas, ear mites, sarcoptic mange, and certain types of ticks in dogs as well as prevent heartworms, fleas, ear mites, hookworms, and roundworms in cats. It also removes 2 types of lungworm in cats and one type of lungworm in dogs. It is distributed by Zoetis, a former Pfizer subsidiary. It is structurally related to ivermectin and milbemycin. Selamectin is not approved for human use.

Drug Indication
Cats and dogs: Treatment and prevention of flea infestations caused by Ctenocephalides spp. for one month following a single administration. This is as a result of the adulticidal, larvicidal and ovicidal properties of the product. The product is ovicidal for 3 weeks after administration. Through a reduction in the flea population, monthly treatment of pregnant and lactating animals will also aid in the prevention of flea infestations in the litter up to seven weeks of age. The product can be used as part of a treatment strategy for flea allergy dermatitis and through its ovicidal and larvicidal action may aid in the control of existing environmental flea infestations in areas to which the animal has access. Prevention of heartworm disease caused by Dirofilaria immitis with monthly administration. The product may be safely administered to animals infected with adult heartworms, however, it is recommended, in accordance with good veterinary practice, that all animals 6 months of age or more living in countries where a vector exists should be tested for existing adult heartworm infections before beginning medication with the product. It is also recommended that dogs should be tested periodically for adult heartworm infections, as an integral part of a heartworm prevention strategy, even when the product has been administered monthly. This product is not effective against adult D. immitis. Treatment of ear mites (Otodectes cynotis). Cats: Treatment of biting lice infestations (Felicola subrostratus)Treatment of adult roundworms (Toxocara cati)Treatment of adult intestinal hookworms (Ancylostoma tubaeforme)Treatment of biting lice infestations (Trichodectes canis)Treatment of sarcoptic mange (caused by Sarcoptes scabiei)

请根据您的实验动物和给药方式选择适当的溶解配方/方案：
1、请先配制澄清的储备液(如：用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液，按从左到右的顺序依次添加助溶剂，澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明，并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀/澄清；向上述体系中加入50 μL Tween-80，混合均匀/澄清；然后继续加入450 μL ddH2O (或 saline)定容至 1 mL；
3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出，可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果，工作液请现配现用！
6、如不确定怎么将母液配置成体内动物实验的工作液，请查看说明书或联系我们;
7、 以上所有助溶剂都可在 Invivochem.cn网站购买。
