透析袋使用方法:
1.先带好手套,把透析袋剪成适当长度(10cm左右)的小段,长度可以根据需要,但必须有足够的容器来容纳。
2.用蒸馏水彻底清洗透析袋,两头用手微微捏住,检查是否有漏袋。透析袋保存液含有防腐剂,对活性物质有抑制作用,至少用蒸馏水(纯水、去离子水均可)反复冲洗三次,有时间最好用蒸馏水浸泡30分钟再使用。
3.不使用的透析膜放回储存液中,密封保存,接触透析膜过程中必须戴手套。
4.使用时,一端用透析袋夹子夹紧,灌满水后,用手指适当加压,检查不漏,另一头也同样反复一次,以免夹子不够紧。然后装入样品,通常要留三分之一至一半的空间,以防透析过程中,袋外的水和缓冲液过量进入袋内将袋胀破。装完样品后,用夹子夹紧袋口,即可进行透析。为了加快透析速度,除多次更换透析缓冲液外,还可使用磁力搅拌器。透析的容器要大一些,可以使用大烧杯、大量筒和塑料桶。根据样品浓度决定透析时间,也可以过夜透析,透析时间在24至48小时为宜。用线吊着透析袋,使透析袋处于悬浮状态,也可以加速透析速度。
