PathDetect Reporter Activator Plasmid
Use pFR-CAT plasmid with PathDetect systems. CAT catalyzes the transfer of acetyl groups from acetyl-coenzyme A to chloramphenicol. The level of background CAT activity in mammalian cells is minimal, as it is a prokaryotic enzyme. The CAT protein is very stable, with a half-life in mammalian cells of ~50 hour as compared with the ~5-hour half-life of luciferase. Various formats for CAT activity assay are available, including isotopic and nonisotopic scintillation and thin-layer chromatography.
