The 5'-nucleotidase considered as a marker enzyme of the plasma membranes shows a highly specific acitvity in both nuclear and mitochondrial-lysosomal fractions of the rat yolk-sac. In isopycnic sucrose gradient fractionation of the mitchondrial-lysosomal fraction a relative accumulation of this enzyme could be shown in the density level of the phagolysosomes (d = 1,16--1,20).
被视为质膜标志酶的5'-核苷酸酶在大鼠卵黄囊的细胞核和线粒体-溶酶体部分均表现出高度特异性活性。在线粒体-溶酶体部分的等密度蔗糖梯度分级分离中，可显示该酶在吞噬溶酶体的密度水平（d = 1.16 - 1.20）相对积累。
