Magnetic Fluid- Carboxyl

  • Catalog No. MF-COO-0030, 0060, 0090
  • Magnetic bead with surface functional group -COOH
  • Carboxyl groups (-COOH)
  • Magnetic Nanoparticle
  • Dextran layer

Magnetic Fluid-Carboxyl is magnetic bead with surface functional group -COOH. The magnetic bead consists of a single-crystal Fe3O4 sphere core and dextran coating layer. Through chemical modification of dextran, the carboxyl groups (-COOH) are joined to the magnetic beads through a short hydrophilic linker. The hydrophilic surface ensures the magnetic beads excellent dispersion ability and easy handling property in a wide variety of buffers.

Through activation of Magnetic Fluid-Carboxyl with EDC, the ligands could be conjugated to the magnetic beads through primary amine groups such as antibody, protein, or peptide.
