Why use Magnosphere?

Core Shell Structure & Uniform Bead Size

Magnosphere™ magnetic beads consist of a core particle, a magnetite layer and a surface polymer layer. Controlled size of the core particle ensures uniform particle size.
Various Surface Designs

Surface Structure Properties
No Iron Oxide Exposure

Magnetic particles were incubated with o-phenylenediamine (OPD) and H₂0₂. OPD coloring was measured to estimate the influence of iron oxide exposure on the immunoassay.
Optimal Performance

Chemiluminescence enzyme immunoassay (CLEIA) for prostate specific antigen (PSA) with MS160/Carboxyl.
