Abstract

SE DESCRIBE UN PROCESO DE ELECTROFORESIS PARA ENFOQUE ISOELECTRICO PARA LA SEPARACION Y PURIFICACION DE UNA ATMOSFERA O COMPUESTO QUIMICO NEUTRO DE UNA O MAS COMPUESTOS QUIMICOS CARGADOS ELECTRICAMENTE. DICHO PROCESO ES ILUSTRADO MAS ABAJO EN EL EJEMPLO DE LA PURIFICACION DE UNA PROTEINA DE LAS PROTEINAS Y SALES CONTAMINANTES. SE PUEDE LLEVAR A CABO EN UN APARATO ESPECIALMENTE DISEÑADO PARA ELLO, ES DECIR UN APARATO COMO SE MIUESTRA EN LA FIG 1. SE DESCRIBE DICHO APARATO Y VARIAS MODIFICACIONES DEL MISMO. LA MEZCLA A SEPARAR ESTA PRESENTE DENTRO DEL FLUJO HIDRAULICO EN LA CAMARA 8. LOS CILINDROS 5 Y 8 CONTIENE GRADIENTES DE PH INMOVILIZADOS O SON SUSTITUIDOS POR MEMBRANAS PH ISOELECTRICA ANFOTERICAS. CADA UNA DE DICHOS GRADIENTE PH Y LAS MEMBRANAS PH TIENEN CONDUCTIVIDA Y AMBOS CAPACIDAD DE TEÑIDO Y TAMPONADO EN SU INTERVALO DE PH. LAS EXTREMIDADES DE DICHOS GRADIENTES O MEMBRANAS PH QUE FORMAN EL TECHO Y EL SUEO DE LA CAMARA 8 TIENEN PUNTO ISOELECTRICOS IGUALES O MAS ALTOS Y MAS BAJOS QUELOS PUNTO ISOELECTRICOS DE LA PROTEINA DE INTERES QUE SE MANTIENE EN SU PUNTO ISOELECTRICO EN EL FLUJO HIDRAULICO Y NO ENTRA SICHAS MEMBRANAS PH Y GRADIENTES PH. CONTRARIAMENTE LAS PROTEINAS Y SALES CONTAMINANTES SON ARRASTRADAS POR UN CAMPO ELECTRICO EN DICHOS GRADIENTES DE PH O A TRAVES DE DICHOS GRADIENTES DE PH O MEMBRANAS DE PH EN LOS DEPOSITOS DE ELECTROLITO 3 Y 14. EL PROCESO DESCRITO TIENE LA VENTAJA DE QUE EL PROCESO DESEADO NO NECESITE SER DETECTADO Y EXTRAIDO DE NINGUNA MATRIZ, ES DECIR, DE DICHOS GRADIENTES DE PH, Y QUE LA RECUPERACION Y PUREZA DEL COMPUESTO DESEADO SEA MAS ALTA.
