Abstract
La presente invención se refiere a un método in vitro para detectar la presencia de anticuerpos neutralizantes de insulina humana recombinante (r HI) mediante análisis de una muestra de suero, caracterizado porque comprende las etapas de: (a) pretratar la muestra de suero para disociar un complejo del anticuerpo con insulina, comprendiendo el pre-tratamiento; i. disociación ácida y tratamiento con carbón vegetal; ii. Neutralizar y tratamiento con PEG; y iii. re- suspensión del sedimento. (b) realizar un ensayo basado en células, en donde el ensayo basado en células comprende las etapas de: i. siembre de células que tienen un receptor por rHI; ii. Nutrición de las células por 18 horas a 26 horas en medio en un medio libre de glucosa; iii. poner en contacto una población de células por pozo con rHI y la muestra de suero pretratada; iv. Lisado de las células y preparación de un lisado claro; y v. evaluación del lisado para fosforilación del receptor de insulina y (c) correlacionar la cantidad de fosforilación con un punto de corte flotante, estando a un nivel de respuesta donde una cantidad de fosforilación que es menor que, o igual que al punto de corte florante, indica que la muestra contiene cantidad de un anticuerpo de rHI.
