By means of enzyme immunoassays based on two monoclonal antibodies with specificities for distinct forms of placental type alkaline phosphatase (Pl-ALP), together with L-leucine inhibition studies, it has been possible to distinguish the Nagao type carcinoplacental enzyme from other placental type alkaline phosphatases. This approach has shown that it is the Nagao type (placental like) enzyme which is detectable in small amounts in the plasma of healthy individuals, particularly cigarette smokers.
借助基于两种对不同形式胎盘型碱性磷酸酶(Pl-ALP)具有特异性的单克隆抗体的酶免疫测定法,以及L-亮氨酸抑制研究,已能够将长野型癌胎盘酶与其他胎盘型碱性磷酸酶区分开来。这种方法表明,正是长野型(胎盘样)酶在健康个体的血浆中,尤其是吸烟者的血浆中能够少量检测到。
