| 目标/特异性 | Detects human Growth Hormone R/GHR in direct ELISAs and Western blots. In direct ELISAs, less than 15% cross-reactivity with recombinant mouse GHR and recombinant rat GHR is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Flow Cytometry: 0.25 µg/106cells Immunohistochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize Growth Hormone R/GHR-mediated inhibition of proliferation in the Nb2‑11 rat lymphoma cell line. The Neutralization Dose (ND50) is typically 0.125-0.5 µg/mL in the presence of 10 ng/mL Recombinant Human Growth Hormone R/GHR Fc Chimera and 0.2 ng/mL Recombinant Human Growth Hormone. |

| 背景 | Growth hormone (GH), also known as somatotropin, is a member of a family of growth factors that includes prolactin, placental lactogens, proliferins and somatolactin (1, 2). It is synthesized primarily by somatotropes in the anterior pituitary and is released as an endocrine hormone. Other cells and tissues, including lymphoid tissues, can also produce GH (3). GH is a pleiotropic molecule which can act directly or indirectly via IGF-I, to regulate growth and metabolism as well as enhance T cell survival and thymic functions (1, 2, 4). GH exerts its biological actions by binding to the GH receptor (GHR) that is present in many cell types (1, 2). Human GHR cDNA encodes a 638 amino acid (aa) residue type I transmembrane protein with an 18 aa putative signal peptide, a 246 aa extracellular domain, a 24 aa transmembrane domain and a 350 aa cytoplasmic domain (5). At least two alternatively spliced isoforms of human GHR, lacking the sequence encoded by exon 3, or lacking most of the cytoplasmic domain, also exist (6, 7). Soluble GH-binding proteins corresponding to extracellular domain of the transmembrane proteins can be generated from the membrane proteins (8). Ligation of GHR by GH has been shown to result in receptor dimerization and activation of the JAK/STAT signaling cascade (9). The soluble GHBP has been shown to interfere with GH signaling by competing with the transmembrane receptor of GH. Alternatively, the GHBP has also been shown to enhance GH action by slowing GH clearance (8, 10). |

Growth Hormone R/GHR Inhibition of Growth Hormone-dependent Cell Proliferation and Neutralization by Human Growth Hormone R/GHR Antibody. Recombinant Human Growth Hormone R/GHR Fc Chimera (Catalog # 1210‑GR) inhibits Recombinant Human Growth Hormone (Catalog # 1067‑GH) induced proliferation in the Nb2‑11 rat lymphoma cell line in a dose-dependent manner (orange line). Inhibition of Recombinant Human Growth Hormone (0.2 ng/mL) activity elicited by Recombinant Human Growth Hormone R/GHR Fc Chimera (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human Growth Hormone R/GHR Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1210). The ND50 is typically 0.125‑0.5 µg/mL. |
