透析袋如何浓缩样品
吹干浓缩法:将蛋白质溶液放入分析袋中,用电风扇吹干。该方法简单但缓慢,温度不宜过高,最好不超过15度。
分析袋浓缩法:用分析袋浓缩蛋白质溶液是最广泛使用的方法。将待浓缩的蛋白质溶液放入透析袋中(没有一个透析袋可以用玻璃纸代替),并加入聚合物(6000-12000),如聚乙二醇(碳蜡)、聚乙烯吡咯、烷酮等。或者将蔗糖喷洒在透析袋外面。吸水剂还可以制成浓度为30%-40%的溶液,可以放入装有蛋白质溶液的透析袋。使用后,吸水剂可以放入保温箱中烘干,也可以自然烘干后重复使用。主要用于替代蛋白质的缓冲液必须有透析袋。不需要特殊的仪器。实验一般采用聚乙二醇20000,简单、快速,对蛋白质无影响。
此外,还有其他样品浓缩方法,如冷冻干燥浓缩法、超滤膜浓缩法等。
