是一種氨基糖苷類抗生素，是穩定轉染最常用的抗性篩選試劑。通過抑制轉座子Tn601，Tn5的基因，干擾核糖體功能而阻斷蛋白質合成，對原核和真核等細胞產生毒素。當neo基因被整合進真核細胞DNA后，則能啟動neo基因編碼的序列轉錄為mRNA，從而獲得抗性產物氨基糖苷磷酸轉移酶的高效表達，使細胞獲得抗性而能在含有G418的選擇性培養基中生長。

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.

Cell（（HepG2.2.15 cells，300 μg/mL G-418 ）

HepG2.2.15 cells were incubated in minimum Eagle’s medium containing 10% FBS and 300 μg/mL G418 (Solarbio, Beijing, China).

Cell（OC cells，800 μg/mL  G418）

PCNP expression plasmid and empty vector, the PCNP shRNA (sh-PCNP group) and scramble shRNA (sh-Scb group) and were transfected into OC cells with Lipofectamine 3000 Transfection Reagent to construct stable cell lines. They were screened, respectively, by G418 (Solarbio, Shanghai, China) at a concentration  of 800 μg/mL and puromycin (Solarbio, Shanghai, China) at a concentration of 2 μg/mL.
