【摘要】 本研究以鱿鱼的成熟精巢为原料，经抽提、水解、沉淀等一系列方法将鱼精蛋白分离出来，并经聚丙烯酰胺等电聚焦电泳分析结果显示，可得到纯度较高的鱼精蛋白。更多还原

【Abstract】 This paper uses adult squid spermatozoa as yaw material, after extracting by 0.5M citric acid, hydrohysising by 0.15M sulphuric acid, precipitating by 30％ trichlotaletic acid, then Protanminc is got. At last deteramine by polyacrinomide-isoelectric forcusing. It Proves the Purity of Protamine is high.更多还原
