Minimate EVO切流過濾系統 (Minimate EVO TFF System)

Minimate™ EVO System 切向流過濾系統是Pall生命科學產品,為高效並可信賴的緩衝液交換或高達 1 公升的樣品濃縮之系統。

商品詳細介紹Product Introduction

用途
1.蛋白質、核酸、病毒、基因治療載體等樣品之濃縮和除鹽
2.回收抗體或重組蛋白質
3.分離大、小生物分子
4.水質、緩衝溶液、培養基之去熱原化
5.處理對鐵不穩定之酵素及分子
6.管柱層析之樣品前處理

原理:

在切流式過濾(Tangential Flow Filtration.TFF)中,樣品流動的方向與濾膜成正切 (Tangent) 的角度,使得樣品可以隨著流速循環,均勻的分散至濾膜面積、有效的避免樣品堆積在濾膜表面,維持一定的流速。

裝置:

樣品從500ml樣品槽底部延著管線經由蠕動幫浦的推動進入壓力計和Minimate TFF Capsule,分子量比Capsule MWCO小的樣品從Filtrate流出,而分子量比Capsule MWCO大的樣品從Retentate流出,再回流至樣品槽內,達到連續性過濾、濃縮、分離、去鹽、透析的步驟。

效率:
Competitive Testing with Cyclooxygenase-2:TFF可省下70%的時間。
