Abstract
METODO DE PRODUCCION DE COMPLEJOS DE LANTANIDO PARAMAGNETICOS DE EFECTO MODIFICADOR DEL CONTRASTE DE UNA IMAGEN MEDICA POR RESONANCIA MAGNETICA NUCLEAR. CONSISTE EN LA COPULACION DE UN ANTICUERPO MONOCLONAL CON UN LIGANDO CAPAZ DE FORMAR COMPLEJO CON UN LANTANIDO PARAMAGNETICO, POR MEZCLA DE UNA DISOLUCION DEL ANTICUERPO EN BICARBONATO SODICO CON UNA DISOLUCION DEL LIGANDO EN DIMETILSULFOXIDO; SEGUIDA DE LA REACCION DEL LIGANDO ASI COPULADO CON UNA SAL O UN OXIDO DE LANTANIDO PARAMAGNETICO; Y, FINALMENTE, SEPARACION DEL COMPLEJO DE LANTANIDO PARAMAGNETICO COPULADO CON DICHO ANTICUERPO MONOCLONAL ASI OBTENIDO. ESTOS COMPLEJOS TIENEN APLICACIONES PARA LA OBTENCION DE IMAGENES DE COMPARTIMENTOS ANATOMICOS, COMO CEREBRO, VIAS BILIARES, ARBOL URINARIO, ETC.
