| Homozygous neoR transgenic mice (TgN3Ems) are viable and fertile with no apparent gross phenotype. The pPGKneobpA transgene has the mouse Pgk1 promoter directing widespread (but not necessarily uniform) expression of neoR: this renders TgN3Ems mice highly G418-resistant and results in a 5-fold increase in the approximate lethal dose of G418 (~480 mg/kg) compared to wildtype mice (~103 mg/kg). Treatment with G418 lethal dose (or higher) in transgenic mice leads to rapid onset of decreased movement, respiratory arrest, and death within minutes. Compared to wildtype mouse embryonic fibroblasts (MEFs), TgN3Ems MEFs exhibit greatly diminished G418 sensitivity: wildtype MEFs show essentially no resistance to G418 while TgN3Ems MEFs survive approximately 20-fold higher G418 levels. Importantly, TgN3Ems heterozygotes and TgN3Ems homozygotes are equally resistant to G418. These TgN3Ems transgenic mice may be useful as source of G418-resistant feeder cells for ge .....
