GE Healthcare Sera-Mag SpeedBeads™ Streptavidin magnetic beads

SpeedBeads Streptavidin exhibit a high affinity when binding to biotinylated ligands such as proteins, nucleic acids and peptides. They respond much faster to a magnetic field to shorten assay times and improve precision and also move faster through viscous solutions.
