General description

Chemical structure: peptidyl nucleoside

Puromycin is a broad spectrum antibiotic produced by Streptomyces alboniger. It is an analog of the 3′ end of aminoacyl-tRNA.[5][6] It is an inhibitor of peptidyl transferase and is active in both prokaryotes and eukaryotes.[6]


Puromycin dihydrochloride from Streptomyces alboniger has been used:
• in the preparation of puromycin stock solution for puromycin sensitivity assay.[2]
• to select lentivirus-infected cells containing puromycin resistant selection marker.[3][4][1]

Puromycin dihydrochloride is a part of the amino-nucleoside family of antibiotics and is derived from Streptomyces alboniger. It is a broad spectrum antibiotic with antitumor activity, as an inhibitor of protein synthesis and has been used to study transcription regulatory mechanisms that control the sequential and coordinate expression of genes during cell differentiation. The recommended working concentration in eukaryotic cell culture is 1-10 μg/mL.

Used as a selective agent for cells that contain the resistance gene puromycin N-acetyl-transferase (PAC). Recommended for use at a range of 1-10 μg/ml. Sterilize stock solution by filtration using 0.22 μm filter then store in aliquots at −20 °C.

Biochem/physiol Actions

Puromycin associates in a non-specific manner with growing polypeptide chains, and thus, leads to premature termination of translation. It inhibits protein synthesis in two ways. It associates with the donor substrate, peptidyl-tRNA, in the P site and thus, functions as an acceptor substrate. Second, it competes with aminoacyl tRNA to bind with the A′ site within the peptidyl transferase center.[6]

作用机制:嘌呤霉素通过提前终止链来抑制蛋白质合成,作为氨基酰基-tRNA 的 3′ 末端的类似物起作用。


抗菌谱:该产品对革兰氏阳性微生物有活性,对耐酸杆菌的活性较低,对革兰氏阴性微生物的活性更低。 嘌呤霉素可以防止细菌、原生动物、藻类和哺乳动物细胞的生长,并且起效迅速,可在 2 天内杀死 99% 的细胞。


As supplied, this product remains active for four years when stored at -20°C.
