It is used to select and maintain eukaryotic cells that are stably transfected with the E. coli hygromycin-resistance gene (hyg or hph). For life science research only. Product Description Formula: C20H37N3O13 LD50: 6 mg/kg in mouse (i.v.);13 mg/kg in guinea pig (i.p.); 63 mg/kg in rat (i.p.) Molecular weight: Mr = 527.5 Working concentration: 50 - 1,000 μg/ml in cell culture. A commonly used concentration for the selection of mammalian cells is 200 μg/ml. However, the optimal concentration must be experimentally determined, since it may vary depending on the type of cell used. Contents Solution, 50 mg/ml, in PBS (phosphate-buffered saline), sterile-filtered Quality Purity: >80% (HPLC) |
