用荧光显微镜研究了日本七鳃鳗（Lampetra japonica）视网膜中与视蛋白（OPS）和视锥蛋白（维斯）抗血清免疫反应的结构的定位。两种抗血清的免疫反应结构不同。玻璃体位于外核层的结构显示OPS样免疫反应，而巩膜位于一个表现出VIS样反应。因此，应用于河七鳃鳗视网膜的两种抗血清允许区分杆和锥免疫反应性光感受器，如通常发生在所有脊椎动物类。前者出现在一种视杆细胞的外节，后者出现在视锥细胞的胞体和轴突中。
The localization of structures immunoreactive to antisera against opsin (OPS; a specific marker for rods) and against visinin (VIS; a specific marker for cones in the vertebrate retina) was investigated in the retina of the river lamprey (Lampetra japonica) by means of fluorescence microscopy. Different immunoreactive structures were found with the two antisera. A vitreadly located structure in the outer nuclear layer displayed OPS-like immunoreactivity, while a scleradly located one exhibited VIS-like reactivity. Thus, the two antisera applied to the retina of the river lamprey permit the distinguishing of rod and cone immunoreactive photoreceptors such as occurs typically in all vertebrate classes. The former appears in the outer segments of a type of rod cells, and the latter in the cell bodies and axons of cones.
