Abstract

Serum proteins of upstream migrants, parasitic adults, early and late metamorphosing animals, and ammocoetes of Petromyzon marinus L. were examined by polyacrylamide gel electrophoresis and crossed-immunoelectrophoresis. The electrophoretic patterns for two proteins, SDS-1 and CB-III, were found to change during the life cycle. quantitative measurements of these two proteins showed that they continued to increase until in the adult they together constituted approx. 85% of the total serum protein. Evidence was obtained for a protein present in ammocoetes and metamorphosing animals, but not in upstream migrants.

摘要

通过聚丙烯酰胺凝胶电泳和交叉免疫电泳对海七鳃鳗(Petromyzon marinus L.)溯河洄游个体、寄生成虫、变态发育早期和晚期个体以及沙隐虫的血清蛋白进行了检测。发现两种蛋白SDS - 1和CB - III的电泳图谱在生命周期中发生变化。对这两种蛋白的定量测量表明,它们持续增加,直至在成体中它们共同构成了约85%的血清总蛋白。有证据表明,一种蛋白存在于沙隐虫和变态发育个体中,但在溯河洄游个体中不存在。
