Abstract

SE PRESENTA UN METODO PARA ENRIQUECER UNA MUESTRA DE SANGRE TOTAL CON CELULAS ESCASAS. UNA MUESTRA DE SANGRE (12) SE DISPONE EN CAPAS EN FICOLL/HYPAQUE-1119 (14) Y SE CENTRIFUGA PARA ELIMINAR LOS ERITROCITOS MATERNOS (16) Y EL RESTO DE LA MUESTRA DE SANGRE CENTRIFUGADA SE HACE PASAR A TRAVES DE UN APARATO SEPARADOR ESTABILIZADO DE CARGA-FLUJO A CONTRACORRIENTE CONTROLADO POR LA GRAVEDAD (20) PARA SEPARAR LOS ERITROCITOS NUCLEADOS FETALES (26) DE LOS DEMAS COMPONENTES CELULARES MEDIANTE LA APLICACION DE UN CAMPO ELECTRICO. LOS ERITROCITOS NUCLEADOS FETALES SEPARADOS (26) SON SOMETIDOS A HEMOLISIS CON AMONIACO (30) PARA ELIMINAR LOS ERITROCITOS MADUROS Y RECUPERAR LOS ERITROCITOS NUCLEADOS FETALES ENRIQUECIDOS.
