级别：Chromatographically pure
活力：≥150units/mg protein
活力定义：One unit will produce 1.0 nanomole of total O-methylated products from 3,4 dihydroxyacetophenone per hour at pH 7.6 at 37℃C。Previous radioactive assay unit definition: One unit will catalyze the methylation of 1.0 nanomole of protocatechuic acid per hr at pH 7.9 at 37℃using S-adenosyl-L-[methyl-14C]methionine as the methyl donor. (~6 radioactive units equal one new unit).
