Streptavidin beads
Streptavidin beads can immobilize biotin-labeled compounds and antibodies, DNA, etc. and can be used in a wide range of applications.
Since Streptavidin does not have sugar chains, there is no non-specific adsorption derived from sugar chains.
Magnetic beads
The product lineup includes regular FG beads and highly magnetically responsive HM beads.
