General description

Chemical structure: aminoglycoside

Application

G418 disulfate is an aminoglycoside antibiotic similar in structure to gentamicin used for selection and maintenance of prokaryotic and eukaryotic cells. Optimal concentrations for selection and maintenance vary by cell lines. Bacteria and algae require 5 μg/mL or less while animal cells may require 300-500 μg/mL.

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.

Caution

The product is stable for two years when stored at 2-8°C.

The methylotrophic yeast, Pichia pastoris, is widely used as a host organism for the expression of heterologous proteins. Currently, the Zeocin and blasticidin resistance genes are the only dominant selectable markers that can be used for primary selection of transformants.

Transcription activation by distal enhancers is essential for cell-fate specification and maintenance of cellular identities. How long-range gene regulation is physically achieved, especially within complex regulatory landscapes of non-binary enhancer-promoter configurations, remains elusive.

FACS Titration of Lentivirus Protocol

FACS (Fluorescence-Activated Cell Sorting) provides a method for sorting a mixed population of cells into two or more groups, one cell at a time, based on the specific light scattering and fluorescence of each cell. This method provides fast, objective, and quantitative recording of fluorescent signals from individual cells.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
