Answer:A carboxymethylated dextran matrix attached to a gold SPR surface.
Answer:Ten Series S Sensor Chip CM5 units.
Answer:No. Excessive surface density can introduce mass-transport or rebinding artifacts.
Series S Sensor Chip CM5 provides a carboxymethylated dextran matrix on a gold SPR sensor surface for versatile covalent ligand immobilization. The hydrophilic dextran layer offers accessible functional groups for coupling proteins, peptides, nucleic acids and other suitable molecules using optimized chemistry. Amine coupling is commonly used to immobilize protein ligands, while alternative workflows accommodate different reactive groups or capture arrangements. This 10-chip Series S package supports repeated SPR experiments across antibody characterization, affinity measurement, fragment screening and concentration analysis. Immobilization density should reflect analyte molecular weight, expected interaction strength and desired kinetic resolution. High ligand loading may increase response but can also increase rebinding or mass-transport artifacts. Prepare an appropriate reference surface and verify regeneration, baseline stability and nonspecific binding before comparing datasets. These chips are measurement surfaces, not chromatographic media or assay reagents; the required immobilization chemicals and running buffer are ordered separately.
