| 靶点 | Bacterial |
| 通路 | Anti-infection |
| 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。 |

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。

In Vitro
Cell（HepG2.2.15 cells，380 µg/mL G-418 sulfate）
Cells were cultured in Dulbecco’s modified Eagle’s medium (DMEM; Solarbio) and supplemented with 10% fetal bovine serum (FBS).G-418 sulfate (380 µg/mL; Solarbio) was added to DMEM with 10% FBS to maintain HepG2.2.15 cells. All cells were incubated at 37°C with 5% CO2.
