Octet® SPR COOH1 Sensor Chip

The Octet® SPR COOH1 sensor chip is comprised of a 2D planar, carboxylated oligoethylene oxide surface which can be used to create a highly stable covalent bond between the sensor chip and desired ligand. The lack of 3D matrix results in a low binding capacity which allows interactions to take place closer to the sensor chip surface. The potential for non-specific binding to positively charged analytes is decreased due to lack of a carboxymethylated dextran matrix. These sensor chips can also be used if interactions are affected by the presence of lectin or dextran.  

Top Features of the Octet® SPR COOH1 Sensor Chip: 

  • Low binding capacity
  • Covalent coupling
  • Matrix length from gold surface: ~2 nm
  • Minimal distance between analyte and planar surface for highly sensitive interactions

Popular Applications for the Octet® SPR COOH1 Sensor Chip: 

  • Intermediate and large molecules
  • Kinetics
