生物活性

G-418 disulfate (Geneticin sulfate), is an aminoglycoside antibiotic, inhibits protein synthesis in eukaryotes and prokaryotes. G-418 disulfate is commonly used as a selective agent for eukaryotic cells^[1].

IC₅₀ & Target

Aminoglycoside

体外研究
(In Vitro)

G418 suLfate 是一种氨基糖苷类新霉素类似物，可干扰蛋白质合成，已广泛用于选择具有新霉素抗性 (NR) 的哺乳动物细胞系。新霉素抗性 (neo) 基因在真核载体中经常用作显性可选择基因。G418 可与脱唾液酸粘蛋白 (AsOR) 共价结合，形成针对肝细胞特异性靶向和毒性的偶联物^[2]。
将人GD3合酶cDNA转染MDA-MB231细胞，采用G-418批量筛选法筛选出稳定过表达GD3合酶的细胞^[2]。氨基糖苷类抗生素 G418 已被证明是许多原核生物和真核生物的抑制剂，浓度为 1-300 μg/mL^[4]。

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
