Product Information
Phase Detail
Biozen MagBeads
Biozen Magbeads is a streptavidin coated paramagnetic affinity bead that can be used to isolate proteins and peptides

Biozen MagBeads

Immunocapture of mAbs Using Magnetic Beads

Biozen MagBeads are used for the purification, clean up, and isolation of proteins and peptide molecules using a paramagnetic affinity bead with a streptavidin coated surface. Magnetic beads offer a rapid solution compared to traditional sample preparation options by maximizing binding capacity with a uniform particle for accurate and reliable results, in less time.

Recommended Use
Consistent purification, clean-up, and isolation of proteins and peptide molecules using a paramagnetic particle

Blocked with hydrophilic copolymer and coupled with biotinylated BSA which:

  • Properly orients capture antibody
  • Prevents surface crowding and ligand inactivation through non-specific binding
  • Enhances dispersion of particles
  • Improves binding efficiency
