Abstract

本发明公开了一种单室脂质体的提取制备。具体步骤如下:首先,准备脂质原料,要求其质量分数不超过百分之五;然后加入适量磷脂,要求其中含有定量比的维他命C和维他命E;薄膜分散法将其溶于乙醇中,摇晃均匀;混入氯仿中,真空状态下贮存过夜;去除有机沉淀物,加入缓冲液;高速震荡,取其上清,即可。所述原料采用逆向蒸发法进行稳定量取。本发明的有益效果是:操作简单,尺寸易控制,制得的质体粒径比较大,而且稳定,制成后贮存期变化小。

Description

一种单室脂质体的提取制备
技术领域
本发明涉及制造领域,具体涉及一种单室脂质体的提取制备。 
背景技术
脂质体(liposome)是一种人工膜。在水中磷脂分子亲水头部插入水中,脂质体疏水尾部伸向空气,搅动后形成双层脂分子的球形脂质体,直径25~1000nm不等。脂质体可用于转基因,或制备的药物,利用脂质体可以和细胞膜融合的特点,将药物送入细胞内部 生物学定义:当两性分子如磷脂和鞘脂分散于水相时,分子的疏水尾部倾向于聚集在一起,避开水相,而亲水头部暴露在水相,形成具有双分子层结构的的封闭囊泡,称为脂质体。 药剂学定义 脂质体 (liposome): 系指将药物包封于类脂质双分子层内而形成的微型泡囊体。常规脂质体进入细胞转运DNA实验,其原理是脂质体增强细胞体的聚集,即加速大分子、荷电多的分子透过膜,该过程相当复杂,尤其在包封较大片段时,在实践中这种技术只在体外使用且要用融合剂,荷电越多用途越少。 
发明内容
本发明要解决的技术问题在于,针对现有技术缺陷,提供一种技术方案:

薄膜分散法将其溶于乙醇中,摇晃均匀;
混入氯仿中,真空状态下贮存过夜;
去除有机沉淀物,加入缓冲液;
高速震荡,取其上清,即可。
本发明中,所述原料采用逆向蒸发法进行稳定量取。 
本发明的有益效果是:操作简单,尺寸易控制,制得的质体粒径比较大,而且稳定,制成后贮存期变化小。 
具体实施方式
