Zusammenfassung
Die Wanderung geladener Teilchen im elektrischen Feld wird zur Trennung komplexer Gemische von Biomolekülen ausgenutzt. Die Trennmethoden werden unter dem Begriff Elektrophorese zusammengefasst. Da die meisten Biomoleküle Ladungen tragen, gehören Elektrophoresen zu den wichtigsten analytischen Methoden. Für die Untersuchung und Charakterisierung komplexer Mischungen sowie zur Überprüfung ihrer Einheitlichkeit sind sie unentbehrlich. Die wesentlichen Unterschiede in den Trennungsmethoden ergeben sich aus dem für jedes Biomolekül charakteristischem Verhältnis von Ladung zu Masse bzw. aus ihrer Molekülgröße und -form.
