描述
In the dialysis method, the sample in question is separated from the “precipitant” by a semi-permeable membrane which allows small reagent molecules to pass but prevents biological macromolecules from crossing the membrane.1-3
Dialysis Buttons are injection molded from polystyrene, and are the size of a small button. The sample is placed in this chamber so as to create a slight dome of liquid at the top of the button. A dialysis membrane is placed over the top of the button/sample and is held in place with an O-ring. The O-ring is held in place by a groove in the Dialysis Button. Dialysis Buttons are supplied with O-rings. The 5 µl to 100 µl sized dialysis buttons have an approximate overall height of 6 mm, an approximate outside diameter of 10 mm without an O-ring in place, and an approximate diameter of 12 mm with an O-ring in place. The 200 µl and 350 µl sized dialysis buttons have an approximate overall height of 8 mm, an approximate outside diameter of 15 mm without an O-ring in place, and an approximate diameter of 17 mm with an O-ring in place. Each package of dialysis buttons includes a plastic golf tee shaped applicator to assist with applying a dialysis membrane to the button and securing with the supplied o-ring.
在透析方法中，有问题的样品通过半透膜与“沉淀剂”分离，半透膜允许小试剂分子通过，但阻止生物大分子穿过膜。1-3
透析按钮由聚苯乙烯注塑成型，大小与小按钮相当。将样品放置在该腔室中，以便在按钮顶部形成一个轻微的液体圆顶。透析膜放置在按钮/样品的顶部，并用 O 形环固定到位。 O 形环由透析按钮中的凹槽固定到位。透析按钮配有 O 形圈。 5 µl 至 100 µl 大小的透析按钮的总高度约为 6 mm，外径约为 10 mm，未安装 O 形圈，直径约为 12 mm，安装了 O 形圈。 200 µl 和 350 µl 大小的透析按钮总高度约为 8 mm，外径约为 15 mm，不带 O 形圈，直径约为 17 mm，带 O 形圈。每个透析按钮包都包括一个塑料高尔夫球 T 形涂抹器，以帮助将透析膜应用到按钮上并使用随附的 O 形圈固定。
