Carboxylated Magnetic Beads

Product Overview

Carboxylated Magnetic Beads are magnetic microspheres functionalized with abundant carboxyl groups on their surface. These functional groups enable the beads to covalently couple with a wide variety of biomolecules such as peptides, proteins, antibodies, and oligonucleotides. These beads are extensively used in biomedical, molecular biology, and bioanalysis applications due to their high reactivity and versatility.

Key Features

• High Surface Area: With their nano or micron-scale particle size, carboxylated magnetic beads offer a large surface area, providing more active sites for biomolecule immobilization and catalytic reactions.
• Surface Carboxyl Functional Groups: Rich in carboxyl groups, these beads allow for covalent bonding with biomolecules through chemical cross-linkers, enhancing their functionality in biomedical applications.
• Good Biocompatibility: Made from biocompatible materials, these beads minimize immune responses and toxicity, making them suitable for both in vitro and in vivo applications.

Applications

• Immunochromatographic Detection: The beads can be surface-modified with antibodies to construct immunochromatographic strips for rapid, sensitive biological detection.
• Biomolecule Immobilization: These beads act as carriers for immobilizing enzymes and other biomolecules, ideal for biochemical reactions and separation processes.
• Drug Delivery: Used as drug carriers, carboxylated magnetic beads can be surface-modified for targeted drug delivery, widely applied in targeted therapies.
• Magnetic Analytical Systems: Combining immunochromatographic technology with magnetic analysis systems, these beads are useful for quantitative rapid detection, such as for human chorionic gonadotropin (hCG), cardiac troponin, and HIV virus detection.
