Carboxyl Magnetic Beads are superparamagnetic beads with high carboxyl content on the surface thus can bind to polypeptides, antibodies or other proteins, oligonucleotides and certain chemical compounds with certain chemical reagent (such as EDC). They are widely used as an important carrier of the medical and molecular biology research tools.
EPRUI Biotech supplies two types of carboxyl treated magnetic microspheres (EPRUI-MagCOOH):
- Carboxyl functionalized magnetic silica beads
- Carboxyl treated magnetic polystyrene microspheres.
Our carboxylized magnetic microspheres have higher magnetic response, lower nonspecific adsorption and richer binding sites with activated groups of carboxyl on the surface, which can easily and efficiently combine with a variety of ligands such as protein, polypeptide, oligomeric nucleotide and drug molecues, especially for batch separation and purification.
