Accession # P40190
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.
Detection of Rat gp130 by Western Blot. Western blot shows lysates of NRK rat normal kidney cell line. PVDF membrane was probed with 2 µg/mL of Mouse Anti-Rat gp130 Monoclonal Antibody (Catalog # MAB5029) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for gp130 at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of gp130 in CD3+ Rat Splenocytes by Flow Cytometry. CD3+ rat splenocytes were stained with Mouse Anti-Rat gp130 Monoclonal Antibody (Catalog # MAB5029, filled histogram) or isotype control antibody (Catalog # MAB002, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # F0101B).

Glycoprotein 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). Rat gp130 shares 88% and 79% aa sequence identity with mouse and human 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).
