Les procédés sont efficaces pour l'identification de composés agonistes ou antagonistes de la fonction du récepteur. Ils mettent en application une méthode de détermination sandwich à deux anticorps utilisant un premier anticorps immobilisé qui se fixe au récepteur et le capture avec les polypeptides et protéines étroitement associés et un deuxième anticorps dirigé contre (i) un déterminant antigénique du récepteur caractéristique de l'état activé mais non de l'état inactivé, (ii) un déterminant antigénique d'une protéine ou d'une molécule fixée caractéristiquement au récepteur activé mais pas au récepteur inactivé ou (iii) un déterminant antigénique du récepteur caractéristique de l'état inactivé mais non de l'état activé. Dans un mode de réalisation, le niveau de fixation du deuxième anticorps est déterminé et mis en corrélation avec la présence du récepteur activé et, de ce fait, avec l'activation en réponse au traitement reçu par les cellules. Les procédés décrits par l'invention sont particulièrement efficaces pour détecter l'activation des récepteurs du facteur de croissance de tyrosine kinase.
