Carboxyl Magnetic Beads

Product Introduction:
Carboxyl magnetic beads are functionalized magnetic nanoparticles that have carboxyl functional groups on their surface. These beads are commonly used in bioconjugation and immunoassay systems. The carboxyl groups provide sites for the easy attachment of various molecules, such as proteins, antibodies, or nucleic acids. The magnetic properties of the beads enable efficient and rapid separation of the bound biomolecules from the mixture by applying an external magnetic field. Overall, carboxyl magnetic beads are versatile tools in molecular biology, biotechnology, and medical research.

Our Products

The carboxyl magnetic beads provided by Alfa Chemistry are composed of polymer and nano iron oxide, which have the advantages of good biocompatibility, superparamagnetism and monodispersity. Their surfaces are rich in carboxyl groups, which can covalently couple peptides, proteins, antibodies and other biological ligands to the surface of the beads under the action of special chemical reagents (such as EDC). They are suitable for solid-phase immunoassay, bacterial detection, high-throughput screening, rapid diagnosis, cell sorting, chemiluminescence, biosensors and other fields.
