Merck, MABE343-AF647, Anti-Puromycin, clone 12D10, Alexa Fluor™ 647 Conjugate Antibody

Puromycin is an aminonucleoside antibiotic, derived from the Streptomyces alboniger bacterium, that functions as a protein synthesis inhibitor that blocks translation through premature chain termination in the ribosome. Monoclonal antibodies to puromycin may be used with standard immunochemical methods to directly monitor translation, a method known as surface sensing of translation (SUnSET). Part of the molecule resembles the 3′ end of the aminoacylated tRNA, making it useful for protein translation analysis. Puromycin induces DNA fragmentation in thymocytes and in human HL-60 leukemia cells.
