Puromycin dihydrochloride


Product overview

  • Name
    Puromycin dihydrochloride
  • Short description
    Protein synthesis inhibitor. Cell culture selection antibiotic.
  • Biological description

    Aminonucleoside antibiotic which disrupts peptide transfer on ribosomes on both prokaryotic and eukaryotic ribosomes to cause premature chain termination during translation.

    Inhibits protein transport of into the mitochondria.

    Also induces apoptosis and shows antineoplastic and antibacterial activity.

    Widely used as a selection antibiotic in cell culture. Puromycin allows the selection of cells that contain the puromycin N-acetyl-transferase gene (PAC) resistance gene.
