Como todavía no se cuenta con una vacuna efectiva a pesar de los esfuerzos realizados por científicos en todo el mundo, la utilización de drogas antirretrovirales para mejorar la calidad de vida de los pacientes es lo que ha resultado más exitoso, de ahí la importancia de poseer medios para realizar un diagnóstico temprano de la infección y para monitorear su progresión con el objetivo de poder actuar sobre ella. El presente trabajo describe la obtención de los componentes biológicos que se requieren para la producción de dos estuches que se utilizan en nuestro país en todos los estudios que tienen relación con la infección VIH-SIDA. Para ello se realizó un protocolo que incluyó varias etapas de purificación e inmovilización de diferentes moléculas. Como resultado se obtuvieron la proteína de 24 Kd del VIH-1 y anticuerpos monoclonales y policlonales humanos contra esta proteína, con adecuados grados de pureza y actividad biológica. La combinación de etapas en este protocolo, permitió ir obteniendo productos que además de utilizarse en la etapa siguiente también por sí mismos, algunos de ellos, constituyeron reactivos de los estuches.]]></p></abstract>
