This Mouse gp130/IL6ST overexpression lysate was created in CHO Cells and intented for use as a Western blot (WB) positive control. Purification of gp130/IL6ST protein (Cat: 50135-M03C) from the overexpression lysate was verified.
A DNA sequence encoding the mouse gp130 (NP_034690.3) extracellular domain (Met 1-Glu 617) was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
The recombinant mouse gp130/Fc chimera is a disulfide-linked homodimer. The reduced monomer consists of 843 amino acids and has a predicted molecular mass of 94.7 kDa. As a result of glycosylation, the apparent molecular mass of rm gp130/Fc monomer is approximately 120-130 kDa in SDS-PAGE under reducing conditions.
Mouse gp130/IL6ST CHO Overexpression Lysate: 使用指南
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Glycoprotein 130 (also known as gp130, IL6ST, IL6-beta, or CD130) is a transmembrane protein that is the founding member of the class of all cytokine receptors. CD130/gp130 is a signal transducer shared by many cytokines, including interleukin 6 (IL6), ciliary neurotrophic factor (CNTF), leukemia inhibitory factor (LIF), and Oncostatin M (OSM). CD130/gp130 functions as a part of the cytokine receptor complex. The activation of this protein is dependent upon the binding of cytokines to their receptors. CD130/gp130 plays a critical role in regulating myocyte apoptosis. Alternatively, spliced transcript variants encoding distinct isoforms have been described. A related pseudogene has been identified on chromosome 17. The receptor systems for IL6, LIF, OSM, CNTF, IL11, CTF1, and BSF3 can utilize gp130 for initiating signal transmission. CD130/gp130 binds to IL6/IL6R (alpha chain) complex, resulting in the formation of high-affinity IL6 binding sites, and transduces the signal. CD130/gp130 may have a role in embryonic development. The type I OSM receptor is capable of transducing OSM-specific signaling events.
