Product Specs

Introduction
Soluble Receptor for Advanced Glycation End products (sRAGE) belongs to the immunoglobulin superfamily and acts as a receptor for diverse ligands. These ligands include amyloid-beta protein, advanced glycation end products (AGEs), members of the S100/calgranulin family, and the amyloidogenic form of serum amyloid A. Located within the major histocompatibility complex (MHC) class III region on chromosome 6, sRAGE exhibits alternative splicing, leading to two transcript variants that encode distinct isoforms. Functionally, sRAGE mediates interactions with nonenzymatically glycosylated proteins, which tend to accumulate in vascular tissues with age and at accelerated rates in individuals with diabetes. Furthermore, sRAGE serves as a receptor for amyloid-beta peptide.
Description

Recombinant Human sRAGE, expressed in E. coli, is a single, non-glycosylated polypeptide chain. It comprises 339 amino acids, resulting in a molecular weight of 36.5 kDa. This sRAGE protein features a 14-amino acid His tag fused at its N-terminus and is purified using proprietary chromatographic methods.

Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation

The protein solution, after sterile filtration (0.4 µm) and concentration (0.5 mg/ml), was lyophilized using a 30 mM acetate buffer at pH 4.

Solubility
To prepare a working solution at a concentration of 0.5 mg/ml, add 0.1 M acetate buffer (pH 4) to the lyophilized pellet and allow it to dissolve completely.
Stability
Store the lyophilized protein at -20°C. After reconstitution, aliquot the product to prevent repeated cycles of freezing and thawing. The reconstituted protein remains stable at 4°C for a limited period.
Purity
Greater than 95% purity as determined by SDS-PAGE analysis.
Synonyms
Advanced glycosylation end product-specific receptor, Receptor for advanced glycosylation end products, AGER, SRAGE, RAGE, MGC22357.

Product Science Overview

Introduction

The Advanced Glycosylation End Product-Specific Receptor (RAGE) is a transmembrane receptor of the immunoglobulin superfamily. It was first characterized in 1992 by Neeper et al. RAGE is known for its ability to bind advanced glycation end products (AGEs), which are proteins or lipids that become glycated after exposure to sugars .

Structure and Function

RAGE is a 35 kilodalton receptor that plays a crucial role in various physiological and pathological processes. It is a multiligand receptor, meaning it can interact with multiple types of molecules, not just AGEs. These interactions are implicated in homeostasis, development, inflammation, and certain diseases such as diabetes and Alzheimer’s disease .

Mechanism of Action

The activation of RAGE on cells such as endothelial cells, mononuclear phagocytes, and lymphocytes triggers the generation of free radicals and the expression of inflammatory gene mediators . This activation leads to a pro-inflammatory state, which is involved in numerous pathological conditions .

Clinical Significance

RAGE is associated with several diseases, including diabetic angiopathy and hyperglycemia . The receptor’s interaction with AGEs and other ligands contributes to the pathogenesis of these conditions by promoting inflammation and oxidative stress.

Research and Applications

Human recombinant RAGE is used in research to study its role in various diseases and to develop potential therapeutic interventions. By understanding how RAGE functions and its interactions with AGEs, scientists aim to find ways to mitigate its harmful effects in diseases like diabetes and Alzheimer’s.
