ChinaPeptides Tech developed the -class technology to prepare a series of magnetic beads including magnetic polymer beads and magnetic silica beads. The magnetic beads have uniform size distribution, er magnetic conetent, and specific surface area. ChinaPeptides Tech’s magnetic beads attached with different functional groups such as hydroxyl (-OH), carboxyl (-COOH) and amine (-NH2) can be applied for target and separation of bioactive substances.
ChinaPeptides Tech's magnetic silica beads have a core-shell structure of magnetic core and silica shell, which are designed for nucleic acid separation and purification. Due to their superparamagnetic properties, the nucleic acids can be directly isolated from complicated biological system by simple mixing of the silica beads and samples.
ChinaPeptides Tech's monodisperse magnetic beads with carboxyl groups can be attached with ligands by specific reagents such as EDC, which are designed to apply for protein purification, cell sorting and affinity chromatography.
