反应种属 | Human |
应用 | Western Blot,Neutralization |
目标/特异性 | Detects human LIF R alpha in direct ELISAs and Western blots. In direct ELISAs, approximately 7% cross-reactivity with recombinant mouse LIF R alpha is observed. |
使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize LIF-induced proliferation in the TF‑1 human erythroleukemic cell line [Kitamura, T. et al. (1989) J. Cell Physiol. 140:323]. The Neutralization Dose (ND50) is typically 6-36 µg/mL in the presence of 0.3 ng/mL Recombinant Human LIF. |

背景 | The activities of the pleiotropic cytokine LIF are mediated through a high-affinity heterodimeric receptor complex consisting of two membrane glycoproteins: an alpha subunit (LIF R alpha, also known as LIF R beta and CD118) that binds LIF with low affinity and the 130 kDa (gp130) subunit that does not bind LIF by itself, but is required for high-affinity binding of LIF by the complex. The gp130 subunit was first described as the signal transducing subunit of the high-affinity IL-6 receptor complex. Besides LIF, the high-affinity heterodimeric LIF receptor complex has been shown to mediate the activities of oncostatin M (OSM), cardiotrophin-1 and ciliary neurotrophic factor (CNTF). Human LIF R alpha cDNA encodes a 1097 amino acid (aa) residue precursor type I membrane protein with a 44 aa residue signal peptide, a 789 aa residue extracellular domain, a 26 aa residue transmembrane domain, and a 238 aa residue cytoplasmic domain. LIF R alpha is a member of the cytokine receptor family and has extensive homology to gp130. The extracellular domain of LIF R alpha has two cytokine receptor domains and three fibronectin type III repeats. In mouse, mRNAs encoding a soluble LIF R alpha and lacking transmembrane and intracellular domains, have been isolated. Soluble LIF R alpha has been shown to bind LIF and has LIF antagonistic activity. |

Cell Proliferation Induced by LIF and Neutralization by Human LIF R alpha Antibody. Recombinant Human LIF stimulates proliferation in the TF‑1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by 0.3 ng/mL Recombinant Human LIF is neutralized (green line) by increasing concentrations of Goat Anti-Human LIF R alpha Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-249-NA). The ND50 is typically 6-36 µg/mL. |
