Product Specs

Introduction
The IL-6 receptor complex consists of two membrane glycoproteins: a low-affinity receptor and a signal-transducing component. The soluble form of the IL-6 receptor (sIL-6R) is present in the urine of healthy adults, the serum of HIV-positive individuals, and the cell culture supernatants of stimulated peripheral blood mononuclear cells (PBMCs). sIL-6R is generated either through proteolytic cleavage from the membrane or as an alternative splice variant.

Product Science Overview

Introduction

Interleukin-6 (IL-6) is a multifunctional cytokine that plays a crucial role in immune response, inflammation, and hematopoiesis. The IL-6 receptor (IL-6R) is composed of two subunits: the IL-6 receptor alpha (IL-6Rα) and the signal-transducing component gp130 (also known as IL-6Rβ or CD130). The IL-6 receptor beta (IL-6Rβ) is essential for IL-6 signal transduction and is involved in various physiological and pathological processes.

Molecular Structure

The IL-6 receptor beta (mouse recombinant) is a single non-glycosylated polypeptide chain containing 187 amino acids . It signals through a cell-surface type I cytokine receptor complex consisting of the ligand-binding IL-6Rα chain and the signal-transducing component gp130 . The recombinant form of IL-6Rβ is produced using E. coli expression systems and is purified to high levels of purity for research purposes .

Biological Function

IL-6Rβ is a critical component of the IL-6 signaling pathway. Upon binding of IL-6 to IL-6Rα, the complex associates with gp130, leading to the activation of intracellular signaling cascades such as the JAK/STAT, MAPK, and PI3K/Akt pathways . These signaling pathways regulate various cellular processes, including cell proliferation, differentiation, and survival.

Applications in Research

Recombinant IL-6Rβ is widely used in immunological research to study the molecular mechanisms of IL-6 signaling and its role in immune modulation . It is also utilized in the development of therapeutic strategies for diseases associated with dysregulated IL-6 signaling, such as autoimmune disorders, chronic inflammatory diseases, and certain cancers .

Preparation and Storage

The recombinant mouse IL-6Rβ protein is typically lyophilized from a 0.2 μm filtered solution in sodium acetate and EDTA with trehalose and BSA as a carrier protein . It is reconstituted at 100 μg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin . The product is shipped at ambient temperature and should be stored at -20 to -70 °C to maintain stability and bioactivity .
