GE Healthcare Sera-Mag SpeedBeads™ Carboxyl Magnetic Beads, hydrophobic

Excellent for coupling oligos or proteins directly to the beads. Their “cauliflower-like” structure gives Sera-Mag beads high binding capacity. The carboxyl groups on these beads can be activated by standard EDC/EDAC chemistry to react with free amino groups, forming amide bonds.
