Gibco Geneticin Selective Antibiotic (G418 Sulfate) is produced by the bacterium Micromonospora rhodorangea and acts by binding the ribosome, thus inhibiting protein synthesis in both prokaryotic and eukaryotic cells. Resistance to Geneticin Selective Antibiotic (G418 Sulfate) is conferred by the E. coli APH (3’) – I and APH (3’) – II resistance genes. Geneticin Selective Antibiotic (G418 Sulfate) is used as a selective antibiotic in the concentration range of 100–200 μg/mL for bacteria, or 200–500 μg/mL for most mammalian cells. This product is supplied as a 50 mg/mL solution in water.

Dual-Site cGMP Manufacturing and Quality Standard
For supply chain continuity, we manufacture Gibco Geneticin Selective Antibiotic (G418 Sulfate) at two separate facilities located in Grand Island, NY, and Scotland, UK. Both sites are compliant with cGMP manufacturing requirements and are certified to the ISO 13485 standard.

常见问题解答 (FAQ)

哺乳动物细胞的稳转筛选过程中可一起使用哪些种类的抗生素(Geneticin,Zeocin,潮霉素B,杀稻瘟素和嘌呤霉素)?

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。

我该如何对我的培养物去污染?

当不可替代的培养物被污染时,研究人员可能会试图控制或消除污染。

1.用户需要确定污染的来源是细菌、真菌、支原体,还是酵母。请点击此处(https://www.thermofisher.com/us/en/home/references/gibco-cell-culture-basics/biological-contamination/bacterial-contamination.h%E2%84%A2l)阅读更多信息,以了解每一种污染的特性。
2.把受污染的培养物跟其他细胞系进行隔离。
3.使用一款实验室消毒剂清洁培养箱和层流柜,并检查HEPA过滤器。
4.高浓度的抗生素和抗真菌剂可能对一些细胞系有毒性。因此,需进行剂量效应测试来确定何种浓度水平的抗生素或抗真菌会造成毒性。这一操作对于使用Gibco Fungizone一类的抗真菌剂或泰乐菌素一类的抗生素尤其重要。

下列操作为我们确定毒性水平和对培养物去污染的推荐步骤:

1.对细胞进行分离,计数, 使用不含抗生素的培养基稀释将细胞稀释至常规传代的浓度。
2.将细胞悬液分入多孔培养板或几个小培养瓶中。向每一培养孔中添加不同浓度的特定抗生素。举例来说,我们推荐以如下浓度测试Gibco Fungizone试剂:0.25,0.50,1.0,2.0,4.0和8.0 µg/mL。
3.每日观察细胞脱落,出现空泡,融汇度降低,细胞变圆一类的毒性效应。
4.一旦确定了抗生素的毒性浓度水平,就可使用比毒性浓度低一至两倍的抗生素浓度来培养细胞两至三代。
5.在不含抗生素的培养基中培养一代。
6.重复步骤4。
7.在不含抗生素的培养基中培养细胞四至六代,以确定污染是否成功被消除。

Which of your antibiotics (Geneticin, Zeocin, Hygromycin B, Blasticidin, and Puromycin) can be used together for stable selection in mammalian cells?

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.

Can Neomycin be used in mammalian selection?  Can Neomycin be used instead of Kanamycin in bacterial selection?

No, Neomycin is toxic to mammalian cells. It also causes irreversible damage to kidneys and other organs. Geneticin (aka G418 Sulfate) is a less toxic and very effective alternative for selection in mammalian cells.  Neomycin can be used in bacterial selection, but Kanamycin is the preferred drug to use because of Neomycin's toxicity.

Cloning and functional expression of a thyrotropin receptor cDNA from rat fat cells.
Authors:Endo T; Ohta K; Haraguchi K; Onaya T;
Journal:J Biol Chem
PubMed ID:7738021
Thyrotropin receptor (TSH-R) has been thought to be thyroid-specific, but, by Northern blot analysis, we found that rat adipose tissue expressed TSH-R mRNAs in amounts approaching those in the thyroid. To investigate the function of TSH-R from adipose tissue, we screened a rat fat cell lambda gt11 cDNA library for ... More

'The cytoplasmic domains of many membrane proteins have short sequences, usually including a tyrosine or a di-leucine, that function as sorting signals.
