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 0.04‑0.2 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 stimulates proliferation in the TF‑1 human erythroleukemic cell line (orange line), as measured by Resazurin (Catalog # AR002). Proliferation elicited by Recombinant Human Oncostatin M/OSM (0.8 ng/mL) is neutralized (green line) by increasing concentrations of Mouse Anti-Human gp130 Monoclonal Antibody (Catalog # MAB228). The ND50 is typically 0.04-0.2 µg/mL.

130 (gp130; also known as IL-6 signal transducer, IL-6 receptor beta,
oncostatin-M alpha subunit) is a ubiquitously expressed, 130 kDa type I
transmembrane glycoprotein and member of the type II subfamily, type I
cytokine receptor family. Functionally, it is responsible for
transduction of the IL-6 signal across the plasma membrane (1). Rat
gp130 is synthesized as a 918 amino acid (aa) precursor with a 22 aa
signal sequence, a 596 aa extracellular domain (ECD), a 22 aa
transmembrane region, and a 278 aa cytoplasmic tail. Eleven potential
N-linked glycosylation sites are found within the rat gp130 ECD (1). The
ECD also contains an N terminal immunoglobulin (Ig)-like C2-type
domain, followed by the cytokine receptor homology region (CHR) which is
made up of two fibronectin type III-like domains and a WSXWS motif, and
three additional fibronectin type III-like domains (2). The domains in
the CHR are the structural hallmarks of the hematopoietic cytokine
receptor family (2). Human gp130 shares 73% and 79% aa sequence identity
with mouse and rat gp130, respectively. Gp130 serves as the signal
transducing receptor subunit for the IL-6-type cytokines consisting of
interleukin (IL)-6, IL-11, leukemia inhibitory factor (LIF), oncostatin M
(OSM), ciliary neurotrophic factor (CNTF), new neurotrophin factor-1
(NNT-1), IL-27, cardiotrophin-1 (CT-1), and cardiotrophin like cytokine
(CLC) (2 - 5). These cytokines are involved in a variety of functions
including the modulation of inflammatory and immune responses, heart
development, fertility, and many other activities (2).
