Product Description

  • Aminonucleoside antibiotic.
  • Protein synthesis inhibitor. Disrupts peptide transfer on ribosomes (acting as an acyl-tRNA analog) causing premature chain termination during translation. Translational inhibitor in prokaryotic and eukaryotic cells in both in vitro and in vivo systems.
  • Inhibits the transport of proteins into the mitochondria in vitro.
  • Reversible inhibitor of dipeptidyl-peptidase II (serine peptidase) and cytosol alanyl aminopeptidase (metallopeptidase).
  • Apoptosis inducer.
  • Inhibits the growth of Gram-positive bacteria, various animal and insect cells. Fungi and Gram-negative bacteria are resistant due to the low permeability to the antibiotic.
  • Antineoplastic agent.
  • Used in cell biology as selective agent in cell culture systems. It allows selection for cells that contain the resistance gene puromycin N-acetyl-transferase (PAC). Puromycin has a fast mode of action, causing rapid cell death at low antibiotic concentrations. Adherent mammalian cells are sensitive to concentrations of 2 to 5 µg/ml, while cells in suspension are sensitive to concentrations as low as 0.5 to 2 µg/ml. Puromycin-resistant stable mammalian cell lines can be generated in less than one week.
