用聚焦层析法测定了牛和大鼠的苯乙醇胺N-甲基转移酶（PNMT）的等电点。牛PNMT具有5种不同的电荷同工酶，范围为5.4至6.2。相比之下，大鼠PNMT仅具有pI 4.8的单一电荷形式。两个物种的PNMT没有共同的等电点，并且等电点没有组织差异。
Isoelectric points (pI) of phenylethanolamine N-methyltransferase (PNMT) from two species, cow and rat, were determined by chromatofocusing. Bovine PNMT has 5 different charge isozymes ranging from 5.4 to 6.2. In contrast, rat PNMT has only a single charge form of pI 4.8. There is no common isoelectric point of PNMT from both species and there is no tissue variation in the isoelectric point.
