Scientific Data Images for Human gp130 Antibody
Cell Proliferation Induced by Oncostatin M/OSM and Neutralization by Human gp130 Antibody.
Recombinant Human Oncostatin M/OSM (Catalog # 295-OM) stimulates proliferation in the TF-1 human erythroleukemic cell line in a dose-dependent manner (orange line). Proliferation elicited by Recombinant Human Oncostatin M/OSM (0.8 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human gp130 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-228-NA). The ND50 is typically 2-10 µg/mL.
Detection of Human gp130 by Western Blot.
Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Goat Anti-Human gp130 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-228-NA) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF017). A specific band was detected for gp130 at approximately 150kDa kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.Applications for Human gp130 Antibody

Background: gp130
Gp130, the common signal transducing receptor component shared by the functional receptor complexes of the IL-6 family of cytokines, belongs to the class I cytokine receptor family. Binding of IL-6 (IL-11) to either the membrane-anchored or soluble IL-6 R (IL-11 R) initiates the association of IL-6 R (IL-11 R) with gp130 which then undergoes homo-dimerization and signal transduction. With other IL-6 family cytokines, such as LIF and OSM, signal transduction is triggered by the hetero-dimerization of gp130 and LIF R or OSM R.
Gp130 is expressed in all organs examined. Soluble gp130, which apparently arises either from proteolytic cleavage of the membrane-bound receptor or from alternative splicing, has been detected in human serum. At the present time, the in vivo functions of soluble gp130 are not clearly understood. In in vitro experiments, natural or recombinant soluble gp130 has been shown to have inhibitory effects on OSM and CNTF activities.
