Abstract
SE DESCRIBE UN SISTEMA DE ENSAYO PARA EVALUAR LOS LUGARES DE ENLACE DE LIGANDOS ESPECIFICOS DESOCUPADOS DE PROTEINAS EN FLUIDOS BIOLOGICOS. EL ENSAYO SE LLEVA A CABO CON UN ELEMENTO DE ENSAYO DE MULTIPLES CAPAS Y SE BASA EN EL PRINCIPIO DE DISTRIBUCION POR EQUILIBRIO SEGUN EL CUAL UN LIGANDO SE DISTRIBUYE A SI MISMO ENTRE LOS LUGARES DESOCUPADOS DE LAS PROTEINAS Y EL RESTO DEL ELEMENTO. EL LIGANDO SE PUEDE ETIQUETAR CON UNA UNIDAD DETECTABLE O SE PUEDE NO ESTAR ETIQUETADO Y DETECTARLO UTILIZANDO OTRAS ESPECIES DETECTABLES. EN UN ASPECTO DE LA INVENCION, SE UTILIZA EL FORMATO DEL ENSAYO PARA ESTIMAR EL NUMERO DE LUGARES EN LA GLOBULINA AGLUTINANTE DE LA TIROXINA (TBG) NO OCUPADOS POR LA TIROXINA (T4) NI LA TRIYODOTIRONINA (T3).
