Abstract
PROCEDIMIENTO ENZIMATICO PARA LA DISOCIACION DE CELULAS DE TEJIDOS ANIMALES Y SU APLICACION. LA INVENCION OBJETO DE ESTA PATENTE CONSISTE EN UN NUEVO METODO DE DISGREGACION DE TEJIDOS ANIMALES, Y EN ESPECIAL DE LOS DEL SNC DE LOS VERTEBRADOS, QUE PERMITE SEPARAR CELULAS VIABLES, CONSERVANDO SU MORFOLOGIA NATIVA, MEDIANTE EL EMPLEO DE PROTEASAS DE STREPTOMYCES FRADIAE Y DE CONDICIONES ESPECIFICAS (BAJA FUERZA JONICA, OSMOLALIDAD ENTRE 175-300 MOSM/KG, PH 6,2-7,4 Y TEMPERATURA DE 32-36C) EN EL PROCESO DE DISGREGACION. ESTOS RESULTADOS, NO ALCANZABLES CON LOS PROCEDIMIENTOS DE DISGREGACION ANTERIORMENTE DESCRITOS, REPRESENTAN UNA MEJORA IMPORTANTE PARA APLICACIONES TALES COMO A) EL USO DE CELULAS DISOCIADAS DEL SNC EMBRIONARIO EN CULTIVOS DE CELULAS PARA ESTUDIOS DE DESARROLLO Y FARMACOLOGICOS, Y TRANSPLANTES NEURONALES; B) UTILIZACION DE NEURONAS Y CELULAS DE GLIA DISOCIADAS DEL SNC ADULTO EN ESTUDIOS ELECTROFISIOLOGICOS Y DE LOCALIZACION FINA DE MOLECULAS EN ESTRUCTURAS SUBCELULARES; Y C) PURIFICACION DE POBLACIONES ESPECIFICAS DE CELULAS PARA ESTUDIOS BIOQUIMICOS Y GENETICOS.
