CDC42结合蛋白激酶α抗体（MRCKα） 洗脱问题

抗体组目前采用的是低pH洗脱方法，按道理说，这个方法应该可以洗脱掉纯大部分抗体，但是有时候出现了一些顽固抗体很难洗脱，大家可以考虑其它的洗脱方法，beads说明书上提到了五大类办法，我觉得比较可靠的方法只有两类，一是改变pH，二是改变离子浓度，另外几种办法要么会带入有机试剂，要么会带入氨基，所以不太适用。改变pH的办法除了用低pH，还可以考虑用高pH来洗脱，好像没多少人尝试过这种办法，在确实没有办法的时候推荐尝试一下。 

CDC42结合蛋白激酶α抗体（MRCKα） 其它问题

1、看了很多抗体纯化的资料，不管是从血清中纯化多抗还是从腹水中纯化单抗，都推荐大家在上柱子之前把血清或腹水稀释2-5倍，另外把血清或腹水采用0.22微米或0.45微米孔径的膜过滤一次。过滤这一步我们是没条件做的了，但是稀释这一步推荐大家试一试，有文献说稀释可以提高回收率

2、封闭这一步做完后，是不是考虑可以用HCl洗一次？连在beads上的蛋白有的是蛋白间非特异性结合上去的，洗脱之前的任何步骤也许都无法洗干净它们，所以这里把它们都洗掉，以免最后都洗到抗体里去了。

3、CNBr活化的琼脂糖或葡聚糖本身的缺陷：这个非特异性结合影响最大的是和血清中的物质结合了。而血清中大部分蛋白都是免疫球蛋白，其中包括我们要的抗体，它们都带有一定的负电，所以都会和这个部位进行非特异性结合，在洗脱前，有一步是用pH5.0的Gly去洗掉与抗原非特异性结合的抗体的，但是它也会洗掉直接与beads非特异结合的蛋白，也包括我们要的抗体，至于这一步会丢掉多少抗体，好像没有人测过。
