    • The present invention relates to a method for determinating cytokine receptor, especially growth hormone receptor (GHR), activation, by the use of an antibody capable of discriminating between an activated and an inactive cytokine receptor conformation, especially GHR or growth hormone binding protein (GHBP) conformation, the method comprising: contacting the antibody and the cytokine receptor to form a complex, contacting a candidate ligand to the complex, measuring the antibody binding to inactive cytokine receptor and thereby discriminating between an activated and an inactive conformation. The invention also relates to an antibody directed to the hinge spanning subdomains I and II of the growth hormone receptor extracellular region and which is capable of discriminating between an activated and an inactive receptor conformation. The invention also relates to the use of the antibody for e.g. characterization of growth hormone receptor interactions and for screening for compounds stabilising die dimerization of GHR.
    • 本发明涉及通过使用能够区分活化和非活性细胞因子受体构象的抗体(特别是GHR或生长激素结合蛋白(GHBP))来确定细胞因子受体,特别是生长激素受体(GHR)的活化的方法 )构型,所述方法包括:使抗体和细胞因子受体接触以形成复合物,使候选配体与复合物接触,测量与非活性细胞因子受体结合的抗体,从而区分活化和非活性构象。 本发明还涉及针对跨越生长激素受体细胞外区域的亚结构域I和II的铰链的抗体,其能够区分活化和非活性受体构象。 本发明还涉及抗体用于例如抗体的用途。 生长激素受体相互作用的表征和用于筛选稳定GHR的二聚体化合物的化合物。
