Eukaryotic selection puromycin
WebPuromycin works by inhibiting peptidyl transfer on both prokaryotic and eukaryotic ribosomes; resistance is conferred by the expression of the pac gene. Used in cell … Puromycin is used in cell biology as a selective agent in cell culture systems. It is toxic to prokaryotic and eukaryotic cells. Resistance to puromycin is conferred by the pac gene encoding a puromycin N-acetyl-transferase (PAC) that was found in a Streptomyces producer strain. Puromycin is soluble in water (50 mg/ml) as colorless solution at 10 mg/ml. Puromycin is stable for one year as solution when stored at -20 °C. The recommended dose as a selection agent in …

We designed an all-in-one PiggyBac system PB-CRISPR to deliver both hSpCas9 and gRNA, along with a puromycin-resistant gene for drug selection (Fig. 2 A).We first tested this system in protein-coding genes that are expressed in hPSCs (Fig. 2 B–H and …
WebAug 26, 2024 · Puromycin is an amino-acyl transfer RNA analog widely employed in studies of protein synthesis. Since puromycin is covalently incorporated into nascent polypeptide chains, anti-puromycin immunofluorescence enables visualization of nascent protein synthesis. WebThe recommended dose as a selection agent in cell cultures is within a range of 1-10 g/ml, although it can be toxic to eukaryotic cells at concentrations as low as 1 g/ml. …
