We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.Reference:

洗脱条件比较剧烈,最后收集的蛋白质很有可能变性,或者是复性困难。 这种洗脱条件剧烈的Protein A 柱结合的重组蛋白质A一般具有5个串联结构域:E、D、A、B、C。这种重组蛋白A虽然除去了不重要的非结合域,仅由5个结构域组成,每个域均可以和IgG的Fc段结合,但不同的域结合强度略有差异。因此洗脱条件不均一,而且经常需要较低的pH值。如果减少串联结构域的个数,并且采取同型结构域串联,就可以避免不同结构域与抗体Fc 段亲和性的差异,洗脱条件会温和而均一。为此,我们可以做一个试验,比较一下
