One MBU is defined as the amount of enzyme required to dephosphorylate 1μg of pGEM® DNA with 3´ overhangs in 15 minutes at 37°C in a 50μl reaction using any Promega restriction enzyme buffer (except F). Dephosphorylation is defined as preventing >95% of the plasmid from ligating (analyzed by agarose gel electrophoresis).
