  • By using a weak/moderate mPGK promoter to drive the antibiotic selection marker (puromycin resistance) and carefully arranging the conditional reporter genes, the selection marker is reliably expressed without compromising conditional expression of rFLuc and GFP. (systembio.com)
  • A cluster and humans coming into contact with the animals (farm that includes three genes, vanH , vanA , and vanX , is required for high-level resistance to glycopeptides. (cdc.gov)
  • The actual origins of acquired resistance genes are unknown, but environmental microbes, including the strains producing antimicrobial agents, are believed to be important sources (4,5). (cdc.gov)
  • A comprehensive understanding of gene expression in human RB is essential for the development of safe and effective new therapies. (molvis.org)
