生物活性: 靶点:Bacterial
通路:Anti-infection
背景说明:是一种氨基糖苷类抗生素,是稳定转染最常用的抗性筛选试剂。通过抑制转座子Tn601,Tn5的基因,干扰核糖体功能而阻断蛋白质合成,对原核和真核等细胞产生毒素。当neo基因被整合进真核细胞DNA后,则能启动neo基因编码的序列转录为mRNA,从而获得抗性产物氨基糖苷磷酸转移酶的高效表达,使细胞获得抗性而能在含有G418的选择性培养基中生长。
生物活性:G-418 disulfate 是与 gentamicin B1 的结构相似的氨基糖苷类抗生素,在原核和真核细胞的蛋白质合成过程中,能够阻止蛋白质的延伸阶段,从而抑制蛋白质的合成[1-3]。
In Vitro:G418是许多原核和真核生物的抑制剂,浓度为1-300微克/毫升。由编码氨基糖苷类3'-磷酸转移酶的Tn5的neo基因对G418的抗性,APT 3'II通常用于实验室研究以选择基因工程细胞[1]。通常,对于细菌和藻类,使用5mg/L或更低的浓度,对于哺乳动物细胞,使用约400mg/L的浓度进行选择,使用200mg/L进行维持。抗性克隆的选择可能需要1到3周[2]。
In Vivo:连续三天G418(40和80 mg/kg)足以消除感染小鼠中所有未转染的布氏疱疹病毒寄生虫[3]。
动物实验:为了表征锥虫群体对G418体内的敏感性,布氏布鲁氏菌GUTat 3.1和布氏布鲁氏菌GUTat 3.1/BBR3的血流形式在亚致死辐射的小鼠中分别扩增。在寄生虫血症的第一个峰之前,收集锥虫,并将含有106个锥虫的等分试样腹膜内接种到小鼠中。感染后24小时,将小鼠分成组,并通过腹膜内接种0.2mL药物,以10,20,30,40,50或80mg/kg体重(bw)的剂量用G418处理。在无菌水中。在第一次治疗后24和48小时,以与之前相同的剂量向每组动物施用G418,导致每只小鼠进行三次处理。需要重复药物治疗以确保从小鼠中完全消除未转染的GUTat 3.1寄生虫。然后通过显微镜检查湿血膜每天监测小鼠33天,以检测寄生虫的存在。记录发现寄生虫的动物,然后从实验中取出。
