伯乐Bio-Rad Chelex® 100 Chelating Resin

伯乐Bio-Rad 1422822/1422832Chelex® 100 Chelating Resin, analytical grade, 50–100 mesh, sodium form, 500 g,Chelex®100螯合树脂,分析级,产品说明:

500 g,阳离子交换树脂,钠型,1%交联,50–100干网目尺寸,300–1180µm湿粒尺寸,约3500 MW限制

选择分析级chelex100树脂,一种弱阳离子交换介质,用于螯合,DNA提取用于PCR,以及其他阳离子交换协议。使用这种钠型树脂进行重力或低压色谱分析。

大筛孔树脂适用于制备柱和分批法

二价离子对一价离子的选择性约为5000:1

对过渡金属有很强的吸引力,即使在高浓度的盐溶液中也是如此

使酶失活,包括脱氧核糖核酸酶,这些酶需要二价阳离子才能活动

如有要求,可提供更大容量和特殊包装

Chelex树脂一含 有成对的二乙酸亚胺离子与聚苯乙烯二乙烯基苯载体结合。它们是*的螯合树脂,可以高选择性地结合多价阳离子,并可用于去除样品和缓冲液中的金属离子。

Chelex 100 Chelating Resin, analytical grade, 100–200 mesh, sodium form, 500 g 1422832

500 g, cation exchange resin, sodium form, 1% crosslinkage, 100–200 dry mesh size, 150–300 µm wet bead size, ~3,500 MW limit

Choose analytical grade Chelex 100 Resin, a weak cation exchange media, for chelation, DNA extraction for PCR, and other cation exchange protocols. Use this sodium-form resin for gravity or low-pressure chromatography.

Medium-mesh resin is effective for both preparative and analytical protocols

Selectivity for divalent over monovalent ions is approximately 5,000 to 1

Strong attraction for transition metals, even in highly concentrated salt solutions

Inactivates enzymes, including DNases, that require divalent cations for activity

Larger volumes and special packaging are available upon request
