Binding Beads in this product are 2.8μm single-particle size, monodisperse superparamagnetic beads covalently coupled with streptomycin avidin, which can be used to enrich the target sequence of NGS library. The magnetic bead achieves specific hybridization by fixing the biotin-labeled target-specific probe to streptavidin on the surface of the magnetic bead, thus capturing the target DNA sequence efficiently. Purification Beads are used for purification and recovery of target DNA after enrichment.
