Abstract

METODO DE PREPARACION DE LIPOSOMAS DE ESTEROLES. CONSISTE EN AÑADIR A UNA FASE ACUOSA TAMPONADA UNA FORMA DE SAL DE UN DERIVADO DE ACIDO ORGANICO DE UN ESTEROL, QUE FORMA BICAPAS CERRADAS DE MODO QUE SE CONSTITUYEN VESICULAS COMPLETAMENTE CERRADAS; Y AGITAR LA MEZCLA HASTA LA FORMACION DE UNA SUSPENSION DE VESICULAS MULTILAMINARES. LA FORMACION DE VESICULAS SE FACILITA SI EL TAMPON CONTIENE EL ION OPUESTO DE LA SAL EN DISOLUCION. PARA OCLUIR EN LAS VESICULAS DE ESTEROL UN COMPUESTO SOLUBLE EN AGUA, SE AÑADE A LA FASE ACUOSA ANTES DE LA FORMACION DE LAS VESICULAS. SI EL COMPUESTO ES INSOLUBLE EN AGUA, SE AÑADE DESPUES DE LA FORMACION DE LAS VESICULAS. LAS VESICULAS DE ESTEROLES TIENEN APLICACIONES PARA OCLUIR COMPUESTOS ACTIVOS BIOLOGICAMENTE O QUE PUEDEN ADMINISTRARSE IN VIVO.-
