Pall ForteBio biosensors are coated with a proprietary biocompatible matrix that is uniform and non-denaturing with minimal non-specific binding. The tips are derivatized and ready for use in a diverse set of biomolecular applications. Biosensors can also be customized for unique applications. Multiple layers can be bound and detected, opening a vast array of approaches to detecting and characterizing biological interactions. To date, over 2.5 million biosensor assays have been run on Octet systems, attesting to the high reproducibility, accuracy, precision and robustness of the platform. Octet biosensors are manufactured in a ISO 9001:2008 certified facility.
Each type of Octet Biosensor is designed to analyze specific biomolecular interactions. A range of surface chemistries is available. Refer to the tables below to select the appropriate biosensor for your needs.
