Smartbond Streptavidin Magnetic Beads


  • Smartbond Streptavidin is covalently coupled to the paramagnetic bead via proprietary linkers. The proprietary conjugation chemistry employed produces beads that possess highest biotin binding capacity in the market. These superparamagnetic particles are surface-modified, optimized and validated for use with high-throughput random access magnetic platform analysers in the application of immunodiagnostics.
  • They can also be used for preparing single stranded DNA templates, immobilization of large DNA fragments, purifying sequencing products,  immunoprecipitation, cell isolation, nucleic acid isolation, purification of DNA/RNA binding proteins and protein purification and are more suited for automated processes.

Key Specifications

  • Form: Beads in suspension
  • Concentration: 4 mg/mL
  • Particle Size: 1μm by laser diffraction
  • Binding Capacity: > 200 μg biotinylated IgG/mg beads
  • Size Distribution: CV 5-10%
  • Ferrites: 40% (± 5%)

Key Characteristics

  • Highest biotin binding; outperforms competitors on free-biotin binding capacity
  • Requires less volume than the competition (2.5 times lower) concentration to perform similar assays which is a cost effective solution for developing automated assays
  • Negligible non-specific binding
  • Compatible with broad pH and temperature ranges
  • Uniform size and lot-to-lot reproducibility
