Macrosep Advance Centrifugal Devices: Reduced Spin Time
Protein solutions were processed in each of the Macrosep Advance devices. Average time (minutes) is plotted against mL of remaining product to be filtered using a swinging bucket rotor at 5,000 x g. Solutions are 3K: Protamine Sulfate, 0.1% in 1X PBS; 10K: Cytochrome C, 0.025% in 1X PBS; 30K: IgG, 0.1% in 1X PBS; and 100K: Apoferritin, 0.1% in 1X PBS.
Macrosep Advance Centrifugal Devices: Retention Efficiency
Protein solutions were processed in each of the Macrosep Advance devices. Average percent retention using a swinging bucket rotor at 5,000 x g is displayed for each MWCO. Solutions were 3K: Protamine Sulfate, 0.1% 1X PBS; 10K: Cytochrome C, 0.025% in 1X PBS; 30K: IgG, 0.1% in 1X PBS; and 100K: Apoferritin, 0.1% in 1X PBS.

文献和实验用物理方法处理掉? 建议在你的样品上超滤前选用0.45um的膜过滤一下，这样就不会有这个问题了，长时间有大颗粒或别的杂质进去对膜包可不太好。 (四)问题：我的蛋白14kD，用截流10000的怎么一点都离不下。而且在我只加超纯水时，水也离不下，十分迷惑 你是用超滤离心管吗?水都离心不下，不是离心力不够吧，要不膜用别的什么处理过了变疏水的了。还是选错了型号。 (五)问题：请问Millipore 的超滤管可以反复使用吗? 如果可以的话,第一次使用
millipore超滤离心管想重复使用，请问如何清洗和保存？ 最近使用超滤管，由于管子较贵，想重复用几次，但找不到可靠的资料。不知如何清洗和保存，比如有人说用叠氮化钠，有人说用氢氧化钠，有人说用乙醇浸泡。莫衷一是。很急用。 【回答精要】 使用后用0.1M NaOH泡24h，然后20%乙醇浸泡保存。 这个我是听老板们说的，的确乙醇泡完后孔径会增大，基本就是5-10KD最大，也就是说如果你的蛋白在21KD以上，应该没问题。或者可以不用乙醇泡，用NaOH洗之后
