Abstract

SE DESCRIBEN UN METODO Y UN APARATO DE ELECTROFORESIS DE GELIFICACION EN EL CUAL LA CONFIGURACION Y LA ORIENTACION DEL CAMPO ELECTRICO SE CONTROLA MEDIANTE LA FIJACION DE LINEAS. SE COLOCAN ELECTRODOS ALREDEDOR DE UNA PERIFERIA. UNO O MAS ELECTRODOS, LOS ELECTRODOS TRANSMISORES, SE FIJAN CON UNA DIFERENCIA DE POTENCIAL (PO) PARA ESTABLECER LA ORIENTACION GENERAL Y LA RESISTENCIA DEL CAMPO ELECTRICO. LOS ELECTRODOS RESTANTES SE FIJAN EN POTENCIALES INTERMEDIOS PARA CONTROLAR LA CONFIGURACION DEL CAMPO ESTABLECIDO POR LOS ELECTRODOS TRANSMISORES. EL CAMPO VARIA DE ACUERDO CON EL OBJETO DE LA ELECTROFORESIS, DEPENDIENDO DEL TAMAÑO DE LAS PARTICULAS Y LA INFORMACION A DETERMINAR EN RELACION A LAS PARTICULAS.
