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.
