Description

4-Aminobutylagarose is a functionalized agarose matrix, chemically modified with a 4-aminobutyl spacer arm. This product is a key affinity chromatography medium designed for the immobilization of ligands, particularly those requiring a primary amine for coupling via carboxyl or carbonyl groups. It is essential for researchers and manufacturers in biopharmaceutical development, protein purification, and enzyme immobilization. The matrix offers a stable, hydrophilic support for creating custom affinity resins for the selective isolation of biomolecules.

Application

• Affinity chromatography support for antibody and protein purification.
• Immobilization matrix for enzymes and biocatalysts in industrial processes.
• Solid-phase support for synthesizing custom ligands in research applications.
• Preparation of specialty resins for the isolation of specific cell receptors or binding proteins.
• Tool in diagnostic kit development for capturing target analytes.
• Base material for creating heparin-mimetic or other charged affinity media.

Quality Control

Our 4-Aminobutylagarose is manufactured under a rigorous quality management system. Each batch is tested to ensure consistent performance characteristics, including ligand density, bead integrity, and flow properties. Certificates of Analysis (COA) detailing specific parameters are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C as a suspension in 20% ethanol or a suitable preservative to prevent microbial growth. The product is hygroscopic (moisture-sensitive); ensure the container is sealed properly after each use to maintain stability.
