For over 25 years KinExA® Technology has been used to detect & measure biological interactions in the most physiologically relevant conditions.
KinExA instruments are easy to use and require no expensive consumables like chips, plates, or kits to run experiments.
If you are using SPR, BLI, or LSA, you need KinExA to identify and optimize your lead candidates. KinExA instruments overcome the limit of detection and immobilization presented by other technologies.
