Hydrophilic Streptavidin Magnetic Beads

Hydrophilic Streptavidin Magnetic Beads are 2-3 µm superparamagnetic particles covalently coupled to a highly pure form of streptavidin. The beads can be used to capture biotin labeled substrates including antigens, antibodies and nucleic acids.

  • The strength of the biotin-streptavidin interaction, an association constant (Ka) of 1015 M-1 coupled with the low non-specific binding of streptavidin permits captured substrates to be useful as ligands in subsequent experiments including mRNA isolation and the capture of primary or secondary antibodies
  • Binding capacity: ≥30 µg biotinylated antibody per mg and > 400 pmol of single-stranded 25 bp biotinylated oligonucleotide per mg
  • Quick, small-scale purification of biotinylated oligonucleotides affords higher throughput and efficiency
