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.
What are the recommended concentrations of antibiotics to use for selection in prokaryotes and eukaryotes?
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.
What is the range of specific activity of Hygromycin B?
The specific activity range of Hygromycin B is from 386-482 micrograms/mg.

What solvent is used to prepare your Hygromycin B solution? How should it be stored?
Hygromycin B is supplied as a 50 mg/mL solution in phosphate buffered saline. It is manufactured aseptically and sterile filtered, and is suitable for use in tissue culture applications. We recommend storing it at 2-8 degrees C.
What is the mode of action on the following antibiotics: Blasticidin, Geneticin (G418), Hygromycin, and Zeocin?
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.
