Description

Agarose CAS NO 39346-81-1 is a high-purity linear polysaccharide derived from red seaweed, renowned for its exceptional gelling properties and molecular sieving capabilities. This product is critical for applications requiring precise molecular separation and high-resolution analysis, offering consistent gel strength and low electroendosmosis (EEO). It is an essential material for biotechnology, pharmaceutical, and diagnostic laboratories worldwide. Researchers and quality control professionals rely on its batch-to-batch consistency for reproducible and reliable results in sensitive analytical and preparative techniques.

Application

• Gel Electrophoresis Matrix: Primary matrix for the separation of nucleic acids (DNA/RNA) and large proteins via agarose gel electrophoresis.
• Microbiology & Cell Culture: Used as a solidifying agent for microbial culture media and for cell immobilization in bioprocessing.
• Chromatography Media: Serves as a base matrix for gel filtration, affinity, and ion-exchange chromatography for biomolecule purification.
• Immunodiffusion & Immunoelectrophoresis: Key component in diagnostic kits for antigen-antibody interaction studies and clinical immunology.
• Food & Pharmaceutical Gelling Agent: Employed as a stabilizer and thickener in certain food products and pharmaceutical formulations.
• Tissue Engineering & 3D Bioprinting: Utilized as a biocompatible hydrogel scaffold for cell growth and structural support in biomedical research.

Quality Control

Our Agarose is manufactured under a strict quality management system. Each batch is tested to ensure it meets critical parameters such as gel strength, gelling and melting temperature, sulfate content, and electroendosmosis (EEO). Certificates of Analysis (COA) detailing purity, microbiological load, and performance specifications are provided with every shipment. We can supply grades compliant with general laboratory, molecular biology, and electrophoresis standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the original container is sealed after each use to prevent moisture absorption, which can affect gelling properties.
