Beads are designed to reduce operation times, isolate proteins through affinity binding, and clean equipment. Safer than conducting heat through water, bath beads will not produce dangerous splashes or evaporate which can cause fragile glassware to break. The culturing spheres allow cells to expand and control synthesis. The balls are fabricated in various diameter sizes and materials to meet specific procedure requirements. Requiring less maintenance than alternatives, the beads minimize overall preparation time.

Affinity purification beads and magnets, MagnaBind™
Supplier: Thermo Fisher Scientific
Magnetic beads are a convenient affinity support for a variety of assays, which allow easy purification of the target without columns or centrifugation. After a binding step in an affinity purification procedure, the magnetic particles are easily and rapidly collected by placing the microcentrifuge tube or reaction vessel next an appropriate rare-earth magnet. MagnaBind™ beads respond rapidly to MagnaBind™ magnets but can be easily dispersed and regathered multiple times (ie. they will not irreversibly aggregate) because they do not have any magnetic memory.
