Linker-activated beads for easy user-designed immobilization
MagnaLink™ 4FB Magnetic Beads provide a high surface area activated with Solulink's 4FB linker to enable easy covalent immobilization for user-defined, high-performance affinity purification schemes. MagnaLink™ 4FB 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 4FB linker enables easy and efficient immobilization of any biomolecule premodified with Solulink's complementary HyNic linker (Cat. No. S-1002-105) using Solulink's proprietary linking technology. HyNic-modifed peptides, oligonucleotides, and antibodies form a strong and stable conjugate bond with MagnaLink™ 4FB Magnetic Beads. The MagnaLink™ 4FB Magnetic Beads are validated and optimized for use with high-throughput magnetic platforms as well as for simple benchtop magnetic stands.



  • User-Designed Scheme – 4FB linker is ready to immobilize your biomolecule of interest
  • High Performance – Supported by high surface area and low nonspecific binding
  • Fast (<2 min) Response Time – Saves time and accommodates viscous samples 


  • Design your own affinity purification scheme with your biomolecule of interest.
  • Capture, immobilization, and separation of HyNic-modified biomolecules such as proteins, peptides, antibodies, DNA, RNA oligonucleotides and/or oligosaccharides.
