Cytiva Series S Sensor Chip SA 10/pk

Cytiva Series S Sensor Chip SA 10/pk. Versatile: immobilizes biotinylated peptides, proteins, nucleic acids, or carbohydrates. Ready-to-use: streptavidin is pre-immobilized, ready for fast, high-affinity ligand capture. Robust: streptavidin-biotin is one of the strongest non-covalent interactions in nature. Non-covalent: a convenient alternative for ligands refractory to covalent immobilization. Standardized ligand orientation: controlled biotinylation enables oriented capture. This high-affinity streptavidin (SA) sensor chip immobilizes biotinylated molecules for surface plasmon resonance (SPR) interaction analysis on Biacore systems. Streptavidin-biotin capture. Sensor Chip SA provides a surface of streptavidin covalently attached to a carboxymethyldextran matrix. Dissociation of biotinylated ligands from the surface of the chip is generally negligible during the course of a Biacore analysis because the affinity of streptavidin for biotin is extremely high, with an equilibrium dissociation constant of about 10-15 M. High binding capacity, reproducibility, and chemical resistance give excellent performance over a broad range of applications. The surface of Sensor Chip SA is resistant to 1-minute pulses of many agents commonly used in SPR sensor chip washing and regeneration protocols - GHC-F (Additional S&H or Hazmat Fees May Apply)
