Electrophoresis along cell membranes

L F Jaffe

    Nature
    |February 17, 1977

    Summary

    Bioelectric fields can sort charged molecules within cell membranes using electrophoresis. This study presents a theoretical framework supporting the hypothesis that electrical gradients drive molecular segregation on cell surfaces.
