Images of initial bead plugs formed by a 10.0 s, 351 V/cm injection of 2.8 μm diameter beads, transported by 88 V/cm through a 50 μm id capillary and held in place by two NdFeB magnets as indicated in Fig. 1. The images were collected during electrophoresis at 88 V/cm. SA-Streptavidin, E-Epoxy, Oligo-Oligonucleotide, IgG-antibody, AP-Alkaline phosphatase.
