Sulfuric acid--4,6-diamino-3-{[3-deoxy-4-C-methyl-3-(methylamino)pentopyranosyl]oxy}-2-hydroxycyclohexyl 2-amino-2,7-dideoxyheptopyranoside (2/1)

개요Geneticin (also known as G418, G418 sulfate) is an aminoglycoside antibiotic similar in structure to gentamicin B1, produced by Micromonospora rhodorangea. Geneticin blocks polypeptide synthesis by inhibiting the elongation step in both prokaryotic and eukaryotic cells and is commonly used in laboratory research to select genetically engineered cells. Resistance to Geneticin is conferred by the neo gene from Tn5 encoding an aminoglycoside 3'-phosphotransferase, APH 3'II.

용도Geneticin 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. It is also used to membrane-permeant allosteric effector of hemoglobin therapeutic in cardiovascular diseases and cancer.

일반 설명The optimal concentration of G418 for selection of resistance will vary according to the organism and/or cell type under investigation. In general, the concentration of active drug required for selection is as follows: Dictyostelium sp.: 10-100 μg/ml Plant cells: 10-100 μg/ml Yeast cells: 0.5-1.0 μg/ml Mammalian cells: 0.1-2.0 μg/ml
