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

Octet® SPR sensor chips have been specifically designed to allow generation of robust and reproducible results for every application – from large molecules, molecular complexes, viruses or whole cells to small molecules or antibody fragments.
The Octet® SPR COOH1 sensor chip can be used for whole cell, virus particle and multivalent or large analyte assays. Its matrix-free surface makes it optimal for large molecular weight analytes.
