Highest biotin-binding capacity and exceptional uniformity deliver an ideal bead for high-throughput
MagnaLink™ Streptavidin Magnetic Beads offer the highest biotin-binding capacity on the market combined with exceptional uniformity. Higher binding translates to reduced bead mass required to immobilize a biotinylated sample and lower background noise from nonspecific binding, resulting in better signals and lower net costs.
MagnaLink™ Magnetic Bead—Exceptional Size Uniformity
MagnaLink™ Streptavidin Magnetic Beads are 2.8 micron-sized, super-paramagnetic, hydrophilic polymer–encapsulated (no exposed iron), monodispersed microspheres with a uniform size distribution and a fast (<2 min) magnetic response time. They are stable in colloidal form and in detergents. The key to high biotin binding is in the unique covalently crosslinked streptavidin, based on Solulink’s proprietary linking technology. The high surface area, when combined with our efficient linking chemistry, produces a consistent, ultra-high, biotin-binding bead. MagnaLink™ beads also demonstrate exceptional size uniformity of <5% CV, evident by scanning electron microscopy (SEM). These combined technologies make MagnaLink™ beads the ideal magnetic bead for high-throughput robotic applications.
