Description

Exhibits high affinity for biotinylated target molecules. Cytiva Sera-Mag Streptavidin-Coated Magnetic Particles combine fast reaction kinetics and low non-specific binding for increased throughput and precision. Can be used as a universal base particle for coating ligands to the particle surface.

• Ideal for immunoassay and molecular biology applications, including sample preparation and assay development for genomics and proteomics
• Available with various nominal biotin binding capacities for optimizing assay development
• Low dissociation constant to tightly bound ligands
• Low non-specific binding for greater precision and accuracy
• Even streptavidin coating for reliable results
• Uniform, nominal 1μm diameter provides high surface area and excellent lot-to-lot reproducibility

Streptavidin Coating Targets Biotinylated Molecules
Compounds that are difficult to attach to particle surfaces by conventional means may be amenable to biotinylation. Sera-Mag Streptavidin-Coated Magnetic Particles provide a high biotin-binding capacity along with a strong affinity for targeted, biotin labeled molecules.Fast Magnetic Response Times and Stable Physical Integrity
The core of the particle is made by a free radical emulsion polymerization of styrene and acid monomer. A layer of magnetite is then coated onto this core.
