Product Recommendation: Gastric Mucin​

• Product Name: Gastric Mucin​

• CAS No.: 84082-64-4​

• Source: Extracted and purified from porcine gastric mucosa, primarily composed of high-molecular-weight mucoproteins​

• Appearance: White to slightly yellow fine powder or granular solid​

• Key Specifications:​

• Total Nitrogen Content: 7.0% - 10.0% (complies with NMPA standards)​

• Reducing Substances: Not less than 18.0% of labeled amount​

Core Functional Properties​

1. Gastric Mucosa Protection: Forms a viscous, adhesive protective film on the gastric epithelial surface, physically isolating gastric acid and pepsin from mucosal tissues. It also exhibits inherent anti-pepsin degradation activity, effectively alleviating mucosal irritation .​

1. Biological Compatibility: Derived from natural mammalian tissue, it has excellent biocompatibility with human digestive systems, ensuring good tolerance and minimal adverse reactions .​

1. Stable Physicochemical Properties: Maintains structural integrity and biological activity under normal storage conditions. Compatible with common pharmaceutical excipients (e.g., microcrystalline cellulose, lactose) for diverse formulation development.​

1. Modeling Versatility: Serves as a key component in 3D gastric organoid cultures, supporting the simulation of physiological and pathological processes of gastric mucosa (e.g., intestinal metaplasia research) .​

Primary Application Scenarios​

1. Pharmaceutical & Nutraceutical Industry (Priority Market)​

• Gastrointestinal Therapeutics:​

• Active ingredient in capsules, powders, and compound tablets for treating gastric ulcers, chronic gastritis, and gastritis-induced erosion .​

• Adjuvant therapy for gastroesophageal reflux disease (GERD) by enhancing mucosal barrier function.​

• Formulation Excipient: Acts as a bioadhesive carrier in oral drug delivery systems, prolonging drug retention in the gastric region for improved efficacy.​

2. Biomedical Research​

• Disease Model Construction: Essential for establishing in vitro gastric organoid models to study gastric intestinal metaplasia (GIM) and "inflammation-cancer transformation" mechanisms .​

• Drug Screening Platform: Supports preclinical evaluation of anti-gastric disease drugs, enabling assessment of mucosal repair and anti-metaplasia effects .​

3. Cosmetic & Personal Care​

• Soothing Ingredient: Incorporated into oral care products (e.g., medicated toothpastes, mouthwashes) to relieve oral mucosal irritation and promote healing of minor ulcers.​

• Gastric Mucin - Test Items & Quality Specifications

  Description: Gastric Mucin is a mucoprotein obtained by digestive extraction from porcine gastric mucosa. It appears as a white or slightly yellow powder or fine granules, with a slight special odor of peptone. When triturated with water, it swells into a viscous emulsion. It is commonly used as an anti-ulcer drug for gastric and duodenal ulcers.
