ANTI-PUROMYCIN ANTIBODY CLONE 12D10

General description

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.

Specificity

Demonstrated to react with Human test sample, preincubated with Puromycin. Predicted to react with all species when test sample is incubated with Puromycin.

Immunogen

Puromycin from Streptomyces alboniger

Application

Anti-Puromycin antibody, clone 12D10, detects puromycin incorporated into protein. Monoclonal antibodies to puromycin may be used with standard immunochemical methods.

Quality

Evaluated by Western Blotting in HEK293 cell lysates treated with Puromycin and Cyclohexamide, or with Puromycin only.

Western Blotting Analysis: A 1:25,000 dilution of this antibody detected Puromycin-incorporated neosynthesized proteins in HEK293 cell lysates treated with Puromycin only. This antibody also detected small mounts of Puromycin-incorporated neosynthesized proteins in HEK293 cells treated with Puromycin and Cyclohexamide.

Target description

Puromycin is incorporated in neosynthesized proteins. In the presense of Puromycin only, this antibody detects Puromycin-incorporated neosynthesized proteins at multiple molecular weights. However, a weaker signal is observed in the co-presense of Cycloheximide, an inhibitor of protein biosynthesis in eukaryotic organisms.
