描述：

Hydrophilic Streptavidin Magnetic Beads are 2 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 (1,2). 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 (3,4).

注意事项：

Beads will bind greater than 800 pmol of free biotin per mg and greater than 400 pmol of single-stranded 20 bp biotinylated oligonucleotide per mg or Hydrophilic Streptavidin Magnetic Beads.
