Puromycin Dihydrochloride is an aminoglycoside antibiotic that is isolated from Streptomyces alboniger. Puromycin acts as a protein synthesis inhibitor by incorporating itself into a polypetide chain that has been growing, causing it to prematurely terminate. Puromycin’s primary application is as a gene-selection antibiotic with an important role in gene-editing via CRISPR/Cas9.

This puromycin reagent, which is in the form of hydrochloride salt, has antineoplastic, antitrypanosomal, and antimicrobial properties. It is important to keep Puromycin Dihydrochloride stored in a tightly closed container in a well-ventilated and dry area.



• Selective antibiotic agent for cell culture systems, selection of mammalian cell lines

Puromycin dihydrochloride has been used in the preparation of puromycin stock solution for puromycin sensitivity assay and to select lentivirus-infected cells containing puromycin resistant selection marker. It 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.
