Selection antibiotic: cell culture tested, sterile reagent

Puromycin is an aminonucleoside antibiotic produced by Streptomyces alboniger.

It specifically inhibits peptidyl transfer on both prokaryotic and eukaryotic ribosomes.

This antibiotic inhibits the growth of Gram positive bacteria and various animal and insect cells.

Puromycin can also be used in some particular conditions for the selection of E. coli transformants.

Resistance to puromycin is conferred by the Pac gene encoding a puromycin N-acetyl-transferase [1].

Animal cells are generally sensitive to concentrations from 1 to 10 µg/ml.

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.
