本文采用聚丙烯酰胺凝胶板电泳和圆盘电泳对脉红螺(Rapana venosa)及“强棘红螺”(Rapana peichiliensis)肝脏中的三种同工酶(酯酶、苹果酸脱氢酶、过氧化物酶)进行了电泳研究,并以香螺(Neptunea cumingi)作参照,发现前两者的三种同工酶电泳图谱及扫描曲线完全一致。结合前人的研究资料,认为脉红螺与“强棘红螺”是同一种。 In this paper, polyacrylamide gel plate electrophoresis and disk electrophoresis were used to detect the activities of three isoenzymes (esterase, malate dehydrogenase, lipase and lipase) in the liver of Rapana venosa and Rapana peichiliensis, Peroxidase) were studied by electrophoresis and the reference of Neptunea cumingi was made. The three isoenzyme electrophoresis patterns and scanning curves of the first two were completely consistent. Combined with previous research data, that the red snail and “strong thorn snail” is the same.
