Description

Combines fast reaction kinetics with very low non-specific binding for increased throughput and precision

Applications include automated immunoassays, immunoprecipitation, and protein purification

Streptavidin coating targets Biotinylated Molecules

Compounds that are difficult to attach to particle surfaces by conventional means may be amenable to biotinylation

Provides a high biotin-binding capacity along with a strong affinity for targeted, biotin labeled molecules

The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer

Two layers of magnetite are coated onto this core, resulting in faster magnetic response times

The surface is blocked with a non-surfactant, non-protein based method, to help prevent non-specific binding of proteins
