General description

An aminonucleoside antibiotic that acts as a prokaryotic and eukaryotic protein synthesis inhibitor. Resembles the aminoacyl-adenylyl terminus of aminoacyl-tRNA and competes for binding to the "A site" of the large ribosomal subunit. Its incorporation into a growing polypeptide results in termination of chain elongation and release of the nascent polypeptidyl-puromycin. Useful for selection of mammalian cell lines expressing a transfected pac gene (Streptomyces alboniger), whose product puromycin acetyltransferase, inactivates the drug via acetylation. Induces DNA fragmentation in thymocytes and in human HL-60 leukemia cells. Recommended range for selection of transfected mammalian cells ranges from 1 to 30 µg/ml.
Protein synthesis inhibitor. Inhibits translation by causing premature release of nascent polypeptide chains. Induces DNA fragmentation in thymocytes and in human HL-60 leukemia cells.
Puromycin, CAS 58-58-2, is a protein synthesis inhibitor that causes premature release of nascent polypeptide chains.
