Testing 1...2...3...Testing...

Microspheres offer a highly convenient and flexible system for test and assay reagent development. Many different types of spheres are available to address the diverse and evolving needs of research and commercial aims – polymer, silica, and magnetic, with different surface chemistries in a range of sizes. Beads offer a large specific surface area for binding, permit efficient capture and isolation of target, and they are highly amenable to automation and miniaturization. See our TechNote on Microsphere Selection for tips on choosing beads for different test and assay formats. Please check out our Microsphere Reagent Development Guide, an overview of products that we manufacture for IVD test / assay development, and considerations for products selection and handling,
