Puromycin dihydrochloride is the dihydrochloride salt of puromycin. Puromycin is an aminoglycoside antibiotic that inhibits protein synthesis.
Puromycin blocks protein synthesis after aminoacyl-sRNA formation, and at the same time it leads to the accumulation of small peptides. Both of these effects appear to be due to the splitting of ribosome-bound peptidyl-sRNA,4 which results in release of incomplete peptide chains.[1]. Puromycin, an analog of the 3’ end of aminoacyl-tRNA, causes premature termination of translation by being linked non-specifically to growing polypeptide chains. Puromycin has two modes of inhibitory action. The first is by acting as an acceptor substrate which attacks peptidyl-tRNA in the P site to form a nascent peptide. The second is by competing with aminoacyl-tRNA for binding to the A’ site[2]. When used in minimal amounts, puromycin incorporation in neosynthesized proteins reflects directly the rate of mRNA translation in vitro. Puromycin immunodetection is an advantageous alternative to radioactive amino acid labeling. It allows the direct evaluation of translation activity in single cells by immunofluorescence microscopy and in heterogenous populations of cells by fluorescenceactivated cell sorting[3].
