Amino Magnetic Beads

Product Introduction:
Amino magnetic beads are specialized particles with a magnetic core composed of iron oxide and a surface coated with amino groups (-NH₂). Amino magnetic beads are widely used in various applications such as immunoassays, protein purification, cell isolation, and nucleic acid extraction. They offer high binding capacities and low non-specific adsorption, making them a valuable tool in biotechnology and life sciences research.

Our Products

The amino magnetic beads provided by Alfa Chemistry have the characteristics of superparamagnetism, fast magnetic responsiveness, rich amino functional groups, monodispersity and submicron scale size. They can covalently couple biological ligands such as peptides, proteins, oligonucleotides, drug molecules and glycoproteins to the surface of beads under the action of special chemical reagents, so they are important carrier tools in medical and molecular biology research.

Advantages

Our products provide sufficient binding sites for biomolecule attachment.
Our products enable fast and efficient separation of target molecules or cells from mixtures using a magnetic field.
Our products have good dispersion and resuspension, and improve the convenience of operation.
Our products have good physical and chemical stability to ensure repeatability.

You Need to Know

Do not freeze, dry, or centrifuge our products. These operations will cause the beads to agglomerate, making them difficult to resuspend and disperse, and will affect the chemical activity of the surface functional groups on the beads.
Before using our products, make sure to thoroughly oscillate or ultrasonic to maintain a uniform suspension of the beads.
In the process of use, the magnetic beads can be washed with pure water or buffer solution for 2-3 times to remove the ethanol in the storage solution according to the requirements.
In order to ensure the best experimental results, please select the appropriate ligand for covalent coupling reaction.
Our products need to be used with magnetic separation equipment.
Our products are for research use only.
