KBsphere® Metal Chelating Magnetic Beads feature a superparamagnetic Fe₃O₄ core, with the surface functionalized with chelating ligands (IDA, NTA, TED, etc.) that bind metal ions. These beads are characterized by high iron content and excellent monodispersity.

Product Features:

Fast magnetic response and good monodispersity

Good biocompatibility with low cytotoxicity

Capable of chelating a wide range of metal ions; easy to operate

Applications:

Protein purification

Extraction of trace metal elements

Product Specifications:

Particle size: 200 nm, 1 μm, 3 μm, 5 μm, 10 μm

Concentration: 50 mg/mL

Solvent: DI Water

Surface functional group & density: IDA, NTA, TED, etc., >250 μmol/g

Compatible buffers: PBS, Tris-HCl, H₂O
