产品信息
产品简介 | 青霉素-链霉素-两性霉素B(Penicillin-Streptomycin-AmpHotericin B Solution)混合液是体外培养中常用的抗生素溶液,也叫做“三抗”。其中,青霉素(Penicillin)能够干扰细菌细胞壁的合成,对革兰阳性菌有效;链霉素(Streptomycin)能够与细菌核糖体30S亚单位结合,抑制细菌蛋白质的合成,对革兰氏阴性菌和革兰氏阳性菌均有效,尤其是革兰氏阴性菌;两性霉素B(AmpHotericin B)能与真菌细胞膜上的麦角甾醇结合,导致细胞膜受损,通透性提高,细胞内物质外漏,破坏正常代谢而起抑菌作用,但对细菌无效。青霉素-链霉素-两性霉素B联合使用可以预防绝大部分的细菌和真菌污染。 |
