Streptavidin Magnetic Beads

Streptavidin magnetic beads are superparamagnetic iron oxide-core functional microspheres with high-efficiency covalently conjugated streptavidin protein on the surface. Tailored for the efficient capture and isolation of biotin-labeled molecules, the product enables rapid and stable binding to free biotin or biotinylated ligands and target molecules such as antibodies, nucleic acids and proteins.

Leveraging the ultra-high specific affinity between streptavidin and biotin (dissociation constant Kd ≈ 10⁻¹⁵ mol/L), Heguang SA magnetic beads exhibit outstanding binding efficiency and extremely low non-specific adsorption. Featuring excellent monodispersity and highly uniform particle size, the product delivers sensitive magnetic responsiveness to achieve rapid magnetic separation under an external magnetic field, greatly shortening the experimental operation time.

1.Ultra-high affinity with strong binding performance between streptavidin and biotin.

2.Extremely low non-specific binding modified with high-polymer surface coating.

3.Rapid magnetic response effectively shortens experimental operation time.

4.Excellent stability with uniform particle size and minimal batch-to-batch variation.
