Is neomycin the same as G418?

Is neomycin the same as G418?

G418 is an analog of neomycin sulfate, and has similar mechanism as neomycin. G418 is commonly used in laboratory research to select genetically engineered cells .

What is G418 used for?

Commonly know as G418 or G-418, Gibco Geneticin reagent is an aminoglycoside related to gentamicin, and is commonly used as a selective agent for eukaryotic cells. As an analog of neomycin sulfate, it interferes with the function of 80S ribosomes and protein synthesis in eukaryotic cells.

Is Geneticin the same as gentamicin?

Geneticin is a 2-deoxystreptamine antibiotic that is structurally related to gentamicin. Although not used clinically, it is employed as an antibiotic in molecular genetics experiments.

Can you use G418 instead of neomycin?

Bottom line: Use G418 for single-selection experiments on eukaryotic cells. Use neomycin or kanamycin for single-selection experiments on prokaryotic cells where you are selecting for neomycin resistance genes. Kanamycin should be used over neomycin if elimination of Mycoplasma species from culture is necessary.

How long does hygromycin selection take?

Puromycin usually kills cells in 3 days, G418 in 7 days, hygromycin in 7 days and blasticidin in 5 days. Cells are often split before selection (e.g. 1:3). That’s because selection does not work if cells are too confluent! Cells should not be too sparse either; they would have a difficult time recovering.

Is geneticin and neomycin same?

G418 also known as geneticin, is a broad-spectrum antibiotic that will select mammalian cells expressing the neomycin protein (encoded by the neomycin gene). Neomycin will select bacteria expressing the same protein, but generally the promoter for Neo in mammalian expression plasmids is not usable in bacteria.

Is hygromycin an antibiotic?

Hygromycin B is a water-soluble antibiotic purified from the bacterium Streptomyces hydroscopicus. Hygromycin B acts by binding to the 80S subunit of the bacterial ribosome and inhibiting protein synthesis. Gibco™ Hygromycin B is used as a bacterial selection antibiotic in the concentration range of 200–500 µg/mL.
