    • Method and materials to carry out preparative-scale electrophoretic separations based on the principle of dynamically created non-co-directional effective electrophoretic mobilities are disclosed. The primary application areas of the method are in the separation, purification, enrichment, concentration or conditioning of both small and large molecular weight, weak and strong electrolyte compounds, such as pharmaceuticals, oligo- and polypeptides, proteins, oligonucleotides, etc. These objectives can be achieved based on the use of a secondary chemical equilibrium, alone or in combination with multiple protic and other secondary chemical equilibria. Though such electrophoretic operations could be achieved by other means, such as by conventional zone electrophoresis or isotachophoresis, the method disclosed here can provide greater separation power, simplicity and higher production rates.
    • 公开了基于动态创建的非同向有效电泳迁移率原理进行制备规模电泳分离的方法和材料。 该方法的主要应用领域是分离,纯化,富集,浓缩或调节小分子量和大分子量,弱和强的电解质化合物,如药物,寡聚和多肽,蛋白质,寡核苷酸等。这些目标 可以基于二级化学平衡的使用,单独使用或与多种质子和其他二级化学平衡相结合来实现。 尽管这样的电泳操作可以通过其他方式实现,例如通过常规区域电泳或等速电泳,但是这里公开的方法可以提供更大的分离能力,简单性和更高的生产速率。
