PUROMYCIN

"Researchers commonly use puromycin to select cells that have been genetically altered."

"The addition of puromycin to a cell culture medium can effectively inhibit protein synthesis."

"The mechanism of action of puromycin involves binding to the ribosome and causing premature release of the nascent peptide chain."

"Puromycin-resistant cells can survive in the presence of puromycin, while sensitive cells will die."

"To maintain cells that are sensitive to puromycin, the antibiotic must be added to the growth medium."
