Geneticin disulfate (G418 sulfate) is a potent aminoglycoside antibiotic and selective agent widely used in molecular biology for the selection of genetically modified cells, particularly in transfection experiments. It inhibits protein synthesis in prokaryotes and eukaryotes, making it essential for screening stable transformants. This chemical has a CAS number of 108321-42-2, with the molecular formula C20H40N4O10·2H2SO4 and a molecular weight of 692.71. Store at 2 to 8 °C, and handle with caution: it carries a Danger signal word because it is a respiratory sensitizer that may cause allergy or asthma symptoms or breathing difficulties if inhaled (H334), and it may also cause an allergic skin reaction (H317). Molekula supplies Geneticin disulfate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
