Top Manufacturers of G418 Neomycin for Research and Pharmaceutical Applications

G418 Neomycin An Overview of Manufacturers and Applications

G418, also known as geneticin, is an aminoglycoside antibiotic commonly used in molecular biology as a selective agent in cell culture experiments. Its primary application lies in the selection of genetically engineered cells that have been transfected with neomycin resistance genes. This article explores the significance of G418, its manufacturers, and its applications in research.

Understanding G418 Neomycin

G418 acts by inhibiting protein synthesis in bacteria and eukaryotic cells. As part of its mechanism, it binds to the 30S ribosomal subunit, disrupting the translation process. This property makes it an invaluable tool in molecular biology, particularly in the production of stable cell lines that express foreign genes. When used in conjunction with transfection methods, G418 allows researchers to select cells that have successfully integrated the resistance gene from the antibiotic G418, making it easier to isolate and propagate cells of interest.

Importance in Molecular Biology

The use of G418 is central to the process of creating genetically modified organisms (GMOs) and cell lines. Researchers leverage its selective pressure to enrich populations of cells that carry specific genetic modifications. The ability to select for neomycin-resistant cells is crucial in various fields, including cancer research, gene therapy, and regenerative medicine. By using G418, scientists can ensure that only those cells carrying the desired genetic traits survive and replicate, thereby advancing research and therapeutic applications.
