Series S Sensor Chip NA is designed for high-affinity capture of biotinylated molecules with subsequent analysis of ligand-analyte binding in primarily low molecular weight applications. This product is part of the Biacore Extend product line and is not a standard Biacore consumables product. Reduced nonspecific binding: Series S Sensor Chip NA is an alternative to test when nonspecific binding effects are experienced with Sensor Chip SA. Noncovalent: a convenient alternative for ligands sensitive to covalent immobilization. Ready-to-use: pre-immobilized NeutrAvidin™ sensor chip eliminates need for preparation of coupling reagents and optimization of coupling conditions. Versatile: immobilize biotinylated peptides, proteins, or nucleic acids for oriented capture. Robust: reproducible high-affinity ligand capture and robust capacity for more than 200 cycles. Flexible: supports researchers with preference for NeutrAvidin ligand. NeutrAvidin capture of biotinylated molecules Series S Sensor Chip NA provides a surface of NeutrAvidin covalently attached to a carboxymethylated dextran matrix, which enables immobilization of biotinylated molecules. High binding capacity, reproducibility, and chemical resistance give excellent performance. Responding to customer needs faster with Biacore Extend Sensor Chip NA is one of an expanding range of Biacore Extend products. These sensor chips provide researchers working in nonregulated environments with the convenience of a wider choice of consumables optimized for Biacore applications. What to expect from Biacore Extend product: Ordered as standard products. Same customer support system is used as for a regular product. QC performed, but no Certificate of Analysis/Conformance issued. For some products, lot-to-lot variation might be higher compared to a standard product.
