WORKING CONCENTRATIONS

The working concentrations of puromycin for mammalian cell lines range from 1 to 10 μg/ml.
In a starting experiment we recommend to determine optimal concentrations of antibiotic required to kill your host cell line.
Puromycin quickly kills eukaryotic cells that do not contain the pac gene. Dying cells detach from the plates, allowing easy and early identification of transformant clones.
Suggested working conditions for selection in some mammalian cells are listed below.
