Application: | G-418 Solution is used to select eukaryotic cells that are stably transfected with the neomycin resistance gene (neo), and to maintain the phenotype (neor) of resistant cells. G-418 is also used to eliminate contaminating fibroblasts from mixed cultures. |
Biochem/physiol Actions: | Mode of Action: G418 blocks polypeptide synthesis and protein elongation by inhibiting synthesis at the 70S and 80S ribosomes. Antimicrobial Spectrum: G418 selects for cells stably transfected with an iNOS promoter construct and neomycin resistance gene and shows activity against protozoa and helminthes. |
Features and Benefits: | • Convenient sterile-filtered solution for immediate use – saves valuable time and effort, and avoids potential errors arising from the preparation of sterile working stock solution from G-418 powder. • Consistent quality and potency – shows no lot-to-lot variation in its ability to select resistant cells. • Function tested in a cell culture assay - ensures effectiveness. • Very pure, as indicated by TLC and microbiological assays – allows you to use less antibiotic while producing greater selection pressure. Lack of contaminants means minimal toxicity. • Cost effective, since the selected colonies are stable. Contents Aqueous solution of G-418, 892 μg/mg, filtered through 0.2μm pore size membrane |

Other Notes: | For life science research only. Not for use in diagnostic procedures. |
Preparation Note: | Working concentration: The optimal concentration of G-418 must be determined experimentally and varies with the cell type used. Active weight: >700μg/mg Recommended concentration in cell culture: The optimal concentration of G-418 must be determined experimentally; it varies from 100μg/ml to 1mg/ml, depending on the cell type used. Specific rotation: 104° to 121°, in water (on dry basis, according to USP XXII). |
Quality: | Purity: = 98%, as shown by TLC. Function testing: in cell culture. |
