We are offering Hygromycin B, Streptomyces sp., Cell Culture-Tested (Cat. No. 400050) as a possible alternative. Please read the alternative product documentation carefully and contact technical service if you need additional information.
Unique aminoglycoside antibiotic that inhibits the growth of prokaryotic (bacteria) and eukaryotic microorganisms (yeasts) and mammalian cells. Inhibits protein synthesis at the translocation step on the 70S ribosome and causes misreading of the mRNA. Hph, a gene from E. coli, encodes resistance to hygromycin B and can be isolated and cloned by recombinant DNA techniques. This hygromycin B-resistance gene is particularly useful for identification or selection of recombinant clones in a variety of cell types. Hygromycin B penetrates cells that have been permeabilized by viral infection and can act as an effective antiviral agent. Bioassay: 350-450 units/mg solution.
