MagnaLink™ Streptavidin Magnetic Beads 2.8 µm


MagnaLink™ Streptavidin Magnetic Beads 2.8 µm

Highest biotin-binding capacity and exceptional uniformity deliver an ideal bead for high-throughput

Over the past 10 years, TriLink's streptavidin-coupled MagnaLink™ Beads have been widely used in types of organizations and are regularly cited in papers for diverse manual and automated applications. 

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

 

A powerful combination: highest binding capacity and exceptional 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 Chromalink™ 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.

Advantages

  • Highest Biotin Binding – Supported by unique streptavidin crosslinking
  • Fast (<2 min) Response Time – Saves time and accommodates viscous samples
  • Exceptional Size Uniformity – Makes MagnaLink™ 2.8 µm beads ideal for high-throughput applications  

Applications

  • Capture, immobilization, and separation of biotin-labeled biomolecules such as genomic DNA, RNA, PCR products, oligonucleotides, peptides, or antibodies. We recommend biotinylation with the ChromaLink™ Biotin Labeling Kit (Cat. No. B-9007-105K).
  • High-throughput robotic applications where high biotin-binding loads must be removed or immobilized without the presence of an iron leachate.
  • MagnaLink™ Streptavidin Magnetic Beads are ideally suited for generating single-stranded PCR templates that can dramatically increase hybridization efficiency to complementary probes by removal of the unbiotinylated competing PCR strand.
