  • Isotachophoresis having interacting anionic and cationic shock waves
    Patent number: 8986529
    Abstract: Improved electrophoretic analysis is provided by interaction of anionic and cationic isotachophoresis (ITP) shock waves that propagate toward each other, and analysis of the resulting interaction zones. These shock wave interactions can provide qualitatively different capabilities from conventional ITP methods. Shock wave interaction can enable a single assay to identify analyte and quantify its concentration via isotachophoretic focusing followed by separation of the concentrated analytes via electrophoresis, without any mid-assay alteration of the externally imposed experimental conditions (i.e., no switching, valve operation, etc. during the measurement). As another example, shock wave interaction can enable a single assay to provide coupled ITP processes with different electrolyte concentrations (as in cascade-ITP) in a single simple system (again, without any mid-assay alteration of the externally imposed experimental conditions).
