Description

Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Biochem/physiol Actions

Mode of Action: Puromycin inhibits protein synthesis by causing premature chain termination acting as an analog of the 3′-terminal end of the aminoacyl-tRNA.

Mode of Resistance: Puromycin acetyltransferase is an effective resistance gene.

Antimicrobial Spectrum: This product is active against gram-positive microorganisms, less active against acid-fast bacilli and more weakly active against gram-negative microorganisms. Puromycin can prevent growth of bacteria, protozoa, algae and mammalian cells and acts quickly, killing 99% of cells within 2 days.

Caution

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

Packaging

1 g in glass bottle

25, 100, 250, 500 mg in glass bottle

Preparation Note

This product is soluble in water at 50 mg/mL. A stock solution should be prepared by filtration using a 0.22 μm filter and then stored in aliquots at -20°C. This product is also soluble in methanol at 10 mg/mL.

Application

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.
