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.
