Abstract
LA PRESENTE INVENCION CONSTA DE UN METODO, EQUIPO Y REAGENTES PARA DETECTAR COBALAMINAS EN UNA MUESTRA. EL METODO INCLUYE LA INTRODUCCION EN LA MUESTRA DE UN PRIMER CONJUGADO DE UNA FASE SOLIDA DE LATEX O DE UN MATERIAL SIMILAR UNIDO A UN FACTOR INTRINSECO PURIFICADO POR AFINIDAD CON UN PRIMER GRUPO DE UNION DE AL MENOS TRES ANGSTROMS DE LONGITUD. EL PRIMER CONJUGADO Y LAS COBALAMINAS UNIDAS EN LA MUESTRA SE EXPONEN LUEGO A UN SEGUNDO CONJUGADO DE UNA COBALAMINA UNIDA A UNA ENZIMA DETECTABLE PARA PRODUCIR UN SEGUNDO CONJUGADO UNIDO AL PRIMERO Y UN SEGUNDO CONJUGADO NO UNIDO. SE DETECTA ENTONCES LA ACTIVIDAD DE LA ENZIMA ASOCIADA TANTO CON EL PRIMER CONJUGADO DE LA FASE SOLIDA COMO CON EL SEGUNDO CONJUGADO NO UNIDO. UNIENDO EL FACTOR INTRINSECO PURIFICADO DE AFINIDAD A UNA FASE SOLIDA DE LATEX O DE UN MATERIAL SIMILAR CON UN PRIMER GRUPO DE UNION DE AL MENOS TRES ARMSTRONGS DE LONGITUD, SE PUEDE REALIZAR UNA MUESTRA DE ENSAYE DE ENZIMA, QUE DETECTA LOS NIVELES DE COBALAMINAS EN MUESTRAS DE PACIENTES DENTRO O POR DEBAJO DE ESCALAS NORMALES HALLADAS EN TALES MUESTRAS.
