猪用生长激素(PST)脂质体包封率测定方法的比较

Comparison of Two Determination Methods for Encapsulation Rate of PST Liposomes

试验对测定包封率的两种方法即凝胶柱分离法和鱼精蛋白凝聚法进行了比较,测得PST脂质体的包封率分别为75.26％、84.58％,PST回收率分别为90.4％和98.22％。因此确定了鱼精蛋白法为试验产品包封率的测定方法。

Experiments were conducted to compare the two methods for encapsulation rate determination; mini - column centrifugation method, and protamine aggregation method. The obtained encapsulation rates of PST li-posomes are 75.26% and 84.58% respectively, and the recovery rates of PST are 90.4% and 98.22% respectively. So the protamine aggregation is fixed as the determination method for the encapsulation rate of the product.
