Abstract

A magnetic field, applied perpendicular to the electric field that induces electrophoresis, has a direct effect on the conductivity of the buffer solution and on the ionic fluidity through saturated polymeric electrophoretic strips. Magnetoelectrophoresis of blood serum yields different patterns of globulins as compared with ordinary electrophoresis. Changes in the separation velocities amount to 15–18% for magnetic field intensities in the range 0·8.−1 T.

Sommaire

Un champ magnétique appliqué perpendiculairement au champ électrique induisant l'électrophorèse exerce une action directe sur la conductivité de la solution tampon et sur la fluidité ionique à travers des bandes de polymères électrophorétiques saturées. La magnétoélectrophorèse du sérum sanguin fournit des structures de globulines différentes par rapport à l'électrophorèse ordinaire. Les variations des vitesses de séparation s'élèvent à des taux compris entre 15 et 18% pour des intensités de champ magnétique de la gamme de 8 000 à 10 000 gauss.

Zusammenfassung

Ein Magnetfeld, das man senkrecht auf das elektrische Feld anwendet, das die Elektrophorese erregt, hat cine direkte Auswirkung auf die Leitfähigkeit der Pufferlösung und auf die ionische Fließkraft durch gesättigte polymere elektrophoretische Bänder. Im Vergleich zur normalen Elektrophorese entstehen bei der Magnetelektrophorese des Blutserums unterschiedliche Globulinbilder. Bei Magnetfeldstärken im Bereich von 8 000 bis 10 000 Gauss betragen die Anderungen in der Trenngeschwindigkeit 15 bis 18%.
