China GSBIO Tosyl-Activated Magnetic Beads
Overview
Our GSBIO Tosyl-Activated Magnetic Beads are designed for robust, covalent immobilization of biomolecules. They consist of a superparamagnetic Fe3O4 core, a polymer coating (such as polystyrene or silica) for superior dispersion, and surface Tosyl groups. These groups directly and covalently coupling to primary amines (−NH2) or thiols (-SH) without additional activation. Ideal for immobilizing antibodies, proteins, peptides, and oligonucleotides in applications such as immunoprecipitation, cell sorting, immunoassays, DNA-protein interaction studies, and drug screening.
Features & Benefits
· Direct Covalent Coupling: One-step, stable immobilization.
· High Binding Capacity & Specificity: Ensures high ligand density and minimizes non-specific binding.
· Excellent Performance: Fast magnetic response, mono-dispersity, and stability.
· Reliable Results: Consistent batch-to-batch performance.
