杀稻瘟菌素 S HCl，粉末

我们所有的抗生素（Geneticin，Zeocin，潮霉素B，杀稻瘟素和嘌呤霉素）均可共用于多重稳转细胞系的建立。不过，需要针对每一种抗生素组合来获取杀菌曲线，因为当与其他抗生素联用时，细胞对某一特定抗生素的灵敏性会出现增加的趋势。

All of our antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for making multiple stable cell lines. However, kill curves will need to be performed for each combination of antibiotics since sensitivity to a given antibiotic tends to increase when combined with other antibiotics.

For best results, optimal concentrations for selection should be determined empirically in each unique experiment through dose response curves. However, to get a general idea of concentrations that have worked for individual cell types, please click on the following url: http://www.thermofisher.com/us/en/home/life-science/cell-culture/transfection/selection.html or type in “Selection Antibiotics” into our main search on www.thermofisher.com.

Blasticidin: Nucleoside Inhibits protein synthesis in prokaryotic and eukaryotic cells by interfering with peptidyl transfer reaction of protein synthesis, causing early termination of translation.

Geneticin (G418): Aminoglycoside Blocks protein synthesis in mammalian cells by interfering with ribosomal function.

Hygromycin: Aminocyclitol Inhibits protein synthesis by disrupting translocation and promoting mistranslation.

Zeocin: Intercalates with DNA and cleaves it.

We recommend a pH of 7 or less and half the normal amount of NaCl in your LB media or plates.
