    • According to one embodiment, a method includes co-feeding fluids comprising a leading electrolyte, a trailing electrolyte, and at least one of DNA and RNA to a channel, and applying an electric field to the fluids in a direction perpendicular to an axis of the channel for inducing transverse isotachophoresis. In another embodiment, a method includes co-feeding fluids to a channel. The fluids include a leading electrolyte, a trailing electrolyte, biological objects, at least one of DNA and RNA, and a spacer electrolyte having an electrophoretic mobility that is between an electrophoretic mobility of at least some of the biological objects and an electrophoretic mobility of the at least one of the DNA and the RNA. The method also includes applying an electric field to the fluids in a direction perpendicular to an axis of the channel for inducing transverse isotachophoresis. Other methods of isotachophoresis are disclosed in addition to these.
    • 根据一个实施方案,一种方法包括将包含前导电解质,尾电解质和至少一种DNA和RNA的流体的流体共同输送到通道,以及在垂直于 诱导横向等电泳的通道。 在另一个实施例中,一种方法包括将流体共同供给到通道。 流体包括前导电解质,尾电解质,生物物体,DNA和RNA中的至少一种以及具有电泳迁移率的间隔电解质,所述间隔电解质位于至少一些生物体的电泳迁移率和电泳迁移率之间 至少一个DNA和RNA。 该方法还包括在垂直于通道的轴线的方向上向流体施加电场以诱导横向等速电泳。 除此之外还公开了其他的等速电泳法。
