一般描述


  • 95-98％ 的样品回收率
  • 极高的膜纯度
  • 操作简单 & 防泄漏
  • 体积特定稀释控制
  • 完整 & 即用型包装

Spectrum′ 专有的生物技术级 CE 是一种低蛋白质结合合成膜，有 4 种精确的 MWCO′（MWCO 变体的颜色编码），不含重金属和硫化物污染物。圆柱形管道几何形状可防止样品稀释（与盒式设备相关），并为总体积检索提供开放通​​道。只有 Float-A-Lyzer® G2 可确保 95-98% 的样品回收率，同时保持 99% 的样品纯度和 <1% 的样品稀释度。

带有密封 O 型圈的防漏旋盖可通过随附的移液器轻松取用，以进行上样、过程测试和样本检索，而不会出现针刺的风险。随附的浮动环可改善透析期间的样品浮力和垂直方向。时尚的设计允许在同一个容器中透析多个样品。
不需要额外的套件、浮标或配件。Float-A-Lyzer G2 采用干燥包装，可随时使用，包括所有组件。只需用水冲洗，用移液管上样，然后进行透析。
Spectrum Laboratories 推出 Spectra/Por® Float-A-Lyzer® G2 新一代即用型实验室透析装置，配有超纯生物技术级纤维素酯（CE）膜

Questions

1–3 of 3 Questions  

  1. What is the minimum volume required for loading into this tube? Additionally, what is the pore size of the tube. Is it greater than 100K polymer?

    1 answer

    1. The minimum volume required for loading into this tube is approximately 0.7 - 1.5 ml. Regarding the pore size of the tube, the Repligen Tech Service explains that the pore size is not directly measurable as the membrane consists of a spongy matrix. Instead, the pore size is indirectly based on membrane retention performance, and it is recommended that the molecule to be retained should be 1.5-2x larger than the membrane MWCO. Therefore, the pore size of the tube is not explicitly defined as greater than 100K polymer but is indirectly determined based on retention performance.

  2. Hi, I am trying to extract mega-basepair DNA from low melting agarose gel. If I put the DNA gel plug in the G2 Dialysis Devices and heat up to 65 degree, will the melted gel be able to move out the devices, and the DNA stay remain in the device?

    1 answer

    1. Purification of DNA from agarose is possible using the Float-A-Lyzer G2 when electrolution is applied. However, the DNA will migrate out of the membrane and the agarose will remain. Heating will not melt the agarose. No protocol is available. The end user will have to establish the appropriate buffer and conditions. It is recommended to optimize using several small samples.
