Abstract

SE DESCRIBE UN METODO PARA DISTINGUIR ENTRE CELULAS INTACTAS Y DAÑADAS EN UNA MUESTRA Y, MAS ESPECIALMENTE, EL METODO USA UN COLORANTE DE ACIDO NUCLEICO VITAL PARA TEÑIR SELCTIVAMENTE CELULAS INTACTAS FRENTE A CELULAS DAÑADAS, QUE LUEGO SE PUEDEN RECONTAR Y CLASIFICAR POR MEDIO DE CITOMETRIA DE FLUJO. EL METODO TAMBIEN SE PUEDE UTILIZAR JUNTO CON ANTICUERPOS MONOCLONALES MARCADOS FLUORESCENTEMENTE PARA IDENTIFICAR SIMULTANEAMENTE ANTIGENOS CELULARES.
