蛋白纯化的binding－buffer－和elution－buffer能用多久
蛋白纯化的bindingbuffer和elutionbuffer一般是现配现用的，因为bindingbuffer和elutionbuffer一般都是浓度比较低的溶液，长时间放置容易长菌污染，可以配置成高浓度的母液，在使用时稀释就可以了。

PAK5基因编码功能及结构描述
这个基因编码的蛋白质是ser/thr蛋白激酶pak家族的成员。pak家族成员是rac/cdc42gtpase的效应者，参与调控细胞骨架动力学、增殖和细胞存活信号。该激酶包含一个cdc42/rac1相互作用结合（crib）基序，并且在gtp存在下已被证明与cdc42结合。这种激酶主要在大脑中表达。它能
