Bangs Laboratories of Indianapolis has announced the availability of a new class of particles featuring what the company calls "kinder, gentler" surface chemistries. With surface epoxy groups, these particles permit covalent coupling of antigens, antibodies, haptens, or DNA to their surfaces. Any ligand with primary amino (and other similarly reactive) groups can be bound to these particles quickly and easily. With sizes from approximately 30 nm to more than 6 mm, these new particles are available as methylmethacrylate/epoxy or styrene/epoxy copolymers. They complement Bangs Laboratories' other "easy-to-bind-to" particles with chloromethyl and aldehyde surface groups.
Bangs Laboratories also offers particles in lots of greater than 1,000 (including magnetics) with other sizes, colors, and surface chemistries.
