Octet

Description

The Octet RED96e monitors label-free binding events in real time to calculate on rates (ka), off rates (kd), and affinity constants(KD). Assays are performed using biosensors, reagent and assay kits in 96-well microplates.

The fluidics-free Octet can measure a wide range of sample types; from large biologics to small molecules, purified or in crude form. The Octet RED96e operates with a wide range in temperature (15–40°C). The microplate evaporation cover minimizes sample loss enabling up to 12 hours of unattended run time.
