1、Serva蛋白质电泳产品Serva 蛋白质电泳产品一. SERVALYTTM两性电解质载体 (40% W/V)两性电解质是低分子量的两性离子体。他们是合成的并可组成一系列变化的等电点。在琼脂糖和聚丙烯酰胺凝胶中含有两性电解质,跑电泳时会形成线性pH梯度。两性电解质分子带有净电荷,可以在电极间的电场移动直到到达相应的等电点位置,然后停止移动并形成固定的平台。SERVALYTTM是一种合成混合物,平均分子量在400到1000道尔顿之间。具有如下优点: 由多种聚合体构成而得到的高分离效果 可以在短时间内染色或脱色 清晰的背景,染料的非特异结合非常低 在三氯乙酸中具有很高的溶解度(固定时迅速去除两性电
2、解质) 为了使等电聚焦达到良好的分离效果,需要稳定的pH梯度并且具有广泛并恒定的缓冲能力。由不同等电点的低分子量物质组成的良好的两性电解质混合物在等电点具有良好的传导性。如果能够维持两性电解质的成分,每次实验都能得到可靠的结果并具有良好的可重复性。Serva能够提供以下三类两性电解质:宽pH值:跨度超过3个pH单位(例如SERVALYTTM3-10)窄pH值:跨度为2-3个pH单位(例如SERVALYTTM3-6)超窄pH值:跨度为1个pH单位(例如SERVALYTTM3-4)SERVALYTTM两性电解质载体为40%的水浓缩物,过滤消毒(0.2mm)。通常的工作浓度在3-5%。在4度条件下,
3、未打开的SERVALYTTM可以储存长达三年。T级别的SERVALYTTM两性电解质载体没有过滤消毒,280nm的UV吸收高于分析(analytical)级别的SERVALYTTM两性电解质载体,边缘的缓冲能力也低。SERVALYTTM3-10 IsoDalt (cat. 42951)尤其适于2D-电泳。宽和窄pH值的SERVALYTTM是可以立即使用的。通常不需要与其他pH组分混合。但是有一些例外也需要注意。非常酸(pH2-4)或者非常碱(pH7-9/9-11)可能在聚合时引起问题。我们推荐加入20%SERVALYTTM3-10(cat.42940)。在倒胶前将8ml的酸或者碱SERVALY
4、TTM与2ml的宽pH值SERVALYTTM混合即可。对于超窄pH值SERVALYTTM,我们推荐进行预混合。SERVALYTTM两性电解质载体 (40% W/V)产品名称产品号规格价格(元)SERVALYTTM pH2-442902.0142902.0210ml25ml1500.003080.00SERVALYTTM pH2-1142900.0142900.0210ml25ml1500.003080.00SERVALYTTMpH2-9 Seed-Mix42935.0142935.0242935.0310ml25ml100ml1500.003080.009400.00SERVALYTTM pH
