Detects human gp130 in direct ELISAs and Western blots. In direct ELISAs, less than 2% cross-reactivity with recombinant rat gp130, recombinant mouse gp130, recombinant human (rh) IL-1 sRI, rhIL-1 sRII, rhIL-2 sR beta, rhIL-2 sR gamma, rhIL‑4 sR, and rhIL-6 sR is observed.
Polyclonal Goat IgG
S. frugiperda insect ovarian cell line Sf 21-derived recombinant human gp130 Leu24-Glu619 (Glu619Asp) Accession # P40189
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.70 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize Oncostatin M/OSM-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 2‑10 µg/mL in the presence of 0.8 ng/mL Recombinant Human Oncostatin M/OSM.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
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.

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.
